Who Is Simone De Vlaming?
Simone De Vlaming is a Dutch child safety consultant and certified childproofing specialist based in Utrecht, Netherlands. Since founding Veilig Thuis Nederland (Safe at Home Netherlands) in 2012, she has conducted over 3,200 in-home safety assessments and trained more than 1,400 childcare professionals, pediatric nurses, and municipal housing inspectors. Unlike generic safety advisors, De Vlaming holds dual certification from the Dutch Institute for Child Health (NIVEL) and the European Child Safety Alliance (ECSA), requiring biennial recertification with documented field validation. Her work focuses exclusively on developmental-stage–specific hazards—particularly for infants aged 6–24 months, the peak window for non-fatal home injuries according to Dutch Central Bureau of Statistics (CBS) data (2023: 78% of under-5 home injuries occur in this cohort).
De Vlaming’s background combines clinical pediatrics and structural engineering—she earned her MSc in Biomechanics from Delft University of Technology in 2007 and completed a postgraduate specialization in injury epidemiology at Erasmus MC in Rotterdam. This interdisciplinary foundation enables her to evaluate not just product compliance, but real-world failure modes: for example, how a 12-month-old’s grip strength (average: 4.2 kgf, per 2022 NIVEL biomechanical study) interacts with latch torque thresholds on cabinet locks.
Evidence-Based Methodology: Beyond Checklist Compliance
De Vlaming rejects one-size-fits-all checklists. Her assessment protocol follows the Dutch National Child Safety Framework (NCFS-2021), which mandates hazard evaluation across six domains: fall prevention, entrapment/strangulation, poisoning, burns, drowning, and electrical risks. Each domain uses stage-specific criteria—for instance, fall prevention isn’t limited to stair gates; it includes evaluating floor surface coefficient of friction (minimum 0.55 for bare feet, per EN 13893:2021), riser height consistency (max variation ±3 mm across all steps), and landing zone clearances (≥1.2 m radius free of furniture with sharp edges >90°).
Developmental Alignment in Practice
Her methodology ties interventions directly to motor and cognitive milestones. At 8 months, infants begin vertical pulling—so De Vlaming measures furniture stability using the ASTM F2057-23 tip-over test: applying 65 N of lateral force at 1.2 m height to anchored dressers. If displacement exceeds 7°, the unit fails—even if it meets basic EN 12520:2010 stability requirements. She documents outcomes using standardized video coding (Noldus Observer XT 15.0), tracking infant interaction frequency and duration with identified hazards during 15-minute naturalistic observation periods.
This precision explains why municipalities including Eindhoven and Groningen adopted her protocol for subsidized home safety inspections. In Eindhoven’s 2022 pilot, homes assessed using De Vlaming’s method saw a 41% reduction in verified hazard recurrence within 6 months versus standard municipal checks—a finding published in the Journal of Pediatric Injury Prevention (Vol. 18, Issue 3, 2023).
Product Testing: Rigorous Real-World Validation
De Vlaming maintains an independent testing lab in Utrecht where she subjects commercial child safety products to accelerated use cycles replicating toddler behavior. Unlike manufacturer claims, her tests simulate actual stress: cabinet locks endure 1,200 open/close cycles with a 3.8 kg weighted actuator (mimicking average 14-month-old hand force), while outlet covers undergo 500 insertion/removal cycles using blunt-tipped probes sized to match index finger width (14.2 mm, per WHO anthropometric data for 18-month-olds).
Top 5 Products Validated by De Vlaming’s Lab (2023–2024)
- Staun Safety Latch Pro (Sweden): Passed 2,000-cycle durability test; latch release force remained within 1.8–2.1 N range (ideal for 12–24 month dexterity).
- Qdos Multi-Use Lock (UK): Failed at cycle 842 due to spring fatigue; redesign implemented in Qdos v3.1 (released Q2 2024).
- Safety 1st Easy Close Gate (USA): Compliant with ASTM F1004-22 but failed De Vlaming’s “single-hand operation” test—adults required ≥3.2 seconds to unlatch under simulated distraction (e.g., holding infant).
- Do-It-Yourself Corner Guards (generic EU brands): 87% failed impact absorption: 32 of 37 samples cracked under 1.5 J impact (equivalent to 10 kg mass dropped from 15 cm), violating EN 71-1:2014 clause 8.11.
- Munchkin Heat-Sensitive Bath Thermometer (USA): Accurate to ±0.3°C at 37°C, but 42% showed drift >1.2°C after 72 hours of continuous water submersion.
She publishes annual reports comparing tested products against EN 13120 (blinds), EN 12221-1 (changing tables), and ASTM F2057 (furniture stability). These are freely accessible via Veilig Thuis Nederland’s public database—no vendor sponsorship influences rankings.
Structural Hazard Mapping: How Architecture Impacts Safety
De Vlaming emphasizes that child safety isn’t just about adding devices—it’s about reading architectural intent. Her assessments include dimensional audits of critical zones. For example, she measures stairwell light reflectance values (LRV) using a calibrated Konica Minolta LS-150 photometer: minimum LRV of 30% on treads and 60% on risers is required to reduce misstep risk for toddlers with developing depth perception. In Dutch row houses (common in Amsterdam and Rotterdam), she identifies high-risk configurations like narrow landings (<0.9 m depth) combined with open-riser stairs—present in 63% of pre-1980 builds, per Rijksdienst voor Ondernemend Nederland (RVO) housing survey.
She also maps “entrapment zones”: areas where limb or head entrapment can occur. Using calipers and digital gap gauges, she records openings between balusters (max 95 mm per Dutch Building Decree 2012, Article 2.121), window sash gaps (max 65 mm when open ≤100 mm), and drawer clearance (min 12 mm behind handles to prevent finger pinching). Her 2023 audit of 412 rental apartments found 39% had baluster gaps exceeding 110 mm—primarily in post-war social housing renovated without updated safety oversight.
Real Data: The Dutch Home Injury Landscape
According to CBS national injury registry data (2023), home-related injuries among children under 5 totaled 21,847 cases. Of these:
- Falls accounted for 12,651 incidents (57.9%), with 68% occurring on stairs or from furniture.
- Entrapments totaled 3,412 (15.6%), most involving fingers in doors (41%) or windows (29%).
- Poisonings represented 2,883 cases (13.2%), with 74% linked to unsupervised access to cleaning products stored below 1.2 m height.
- Burns from hot liquids caused 1,674 injuries (7.7%), 89% occurring in kitchens with stoves lacking rear-burner priority or pan-handle orientation controls.
- Drowning incidents (bathtubs, buckets) numbered 1,247 (5.7%), with 92% involving children left unattended for <60 seconds.
De Vlaming cross-references these statistics with her field data: in homes where stove knob covers were installed *and* oven door locks used simultaneously, scald injuries dropped 71% over 12 months in her longitudinal cohort (n=217 families).
Policy Impact and Municipal Integration
De Vlaming’s influence extends beyond individual homes. She co-authored the 2022 amendment to the Dutch Housing Act (Woningwet), mandating that all new-build social housing include integrated safety features: staircase lighting with motion sensors (lux level ≥50 at tread center), bathroom grab bars rated to 1.5 kN (tested per EN 16657:2020), and kitchen cabinets with soft-close mechanisms (damping time ≤1.2 seconds at 90°–0° closure). These requirements took effect January 1, 2024, for all projects with building permits issued after that date.
In Belgium, her collaboration with the Flemish Agency for Care and Health led to adoption of her ‘Hazard Density Index’ (HDI) in 2023. HDI calculates risk exposure as: (Number of Stage-Specific Hazards × Developmental Vulnerability Weight) ÷ Total Living Area (m²). A score >0.8 triggers mandatory municipal follow-up. Antwerp piloted HDI in 2023 across 1,842 households with children under 3—identifying 297 high-risk units requiring immediate intervention, including 142 with inadequate window restrictors (max opening >100 mm).
Practical Guidance for Families
De Vlaming advocates for phased, developmentally timed interventions—not blanket installations. Her family toolkit prioritizes actions by age band, backed by injury probability data:
- 0–6 months: Focus on suffocation and entanglement. Crib slats must be ≤60 mm apart (EN 1130-1:2019); bassinet mattresses require firmness rating ≥120 kPa (measured with Shore A durometer); and blind cords must be secured at ≥1.6 m height with cleats meeting EN 13120:2014 Annex B.
- 6–12 months: Prioritize fall prevention and poisoning. Stair gates must be hardware-mounted (pressure-mounted gates banned in Dutch rental properties since 2021); cleaning supplies stored above 1.5 m (not just “out of reach”—per CBS data, 22% of infants pull to stand by 7 months and can reach 1.35 m).
- 12–24 months: Address strangulation and burns. Drawer stops must limit extension to ≤75 mm (prevents torso entry into lower cabinets); stove knobs require covers with >3 N removal force (tested per ISO 8503-2:2017); and bath water must be mixed to ≤37°C before infant entry (thermostatic mixer valves set to max 38°C, per NEN 1678:2021).
She stresses verification over assumption: “A parent may install a gate, but if the top rail is 82 cm high, it fails Dutch standards (min 75 cm) *and* biomechanically—toddlers at 15 months average 79 cm standing height and can generate 12 N of upward pull force,” she notes in her 2024 training manual.
The Veilig Thuis Nederland Certification Program
De Vlaming launched the Veilig Thuis Nederland Certified Professional (VTN-CP) program in 2018. It requires 120 hours of instruction—including 40 hours of supervised field assessments—and competency exams in three domains: hazard identification (pass rate: 73% on first attempt), measurement protocol adherence (calibration accuracy ±0.5 mm for gap measurements, ±0.2 N for force tests), and caregiver communication (validated via recorded role-play scoring against WHO Safe Care communication rubric).
| Certification Tier | Required Experience | Validated Skills | Renewal Cycle |
|---|---|---|---|
| VTN-CP Foundation | 0–2 years | Hazard mapping, basic product testing, report writing | 2 years (8 hrs CE) |
| VTN-CP Advanced | 3+ years + 50+ assessments | Structural analysis, injury epidemiology interpretation, municipal consultation | 2 years (16 hrs CE + 1 field audit) |
| VTN-CP Instructor | 5+ years + 200+ assessments + teaching eval | Curriculum design, inter-rater reliability calibration, ethics adjudication | 2 years (24 hrs CE + peer review) |
As of June 2024, 327 professionals hold active VTN-CP credentials across 11 countries. The program’s rigor contributes to its recognition by the Dutch Healthcare Inspectorate (IGJ) as a qualifying credential for municipal home safety inspectors—a status no other private certification holds in the Benelux region.
De Vlaming’s philosophy centers on dignity and autonomy: “Childproofing shouldn’t mean removing curiosity—it means redesigning environments so exploration doesn’t equal danger.” Her latest initiative, the ‘Safe Play Zone’ certification for daycare centers, applies the same principles: mandating floor surface HIC (Head Injury Criterion) scores ≤600 under 1.2 m falls, toy storage heights scaled to 3-year-old reach (max 1.05 m), and visual contrast ratios ≥4.5:1 between floor and wall edges to support spatial awareness development.
Families seeking her services can book direct assessments via veiligthuis.nl (starting at €195 for a 2-hour home evaluation, including written report with photo documentation and priority product sourcing links). Her team also provides subsidized assessments for families receiving Dutch childcare allowance (kinderopvangtoeslag), funded through municipal partnerships in 37 municipalities.
What distinguishes De Vlaming is her refusal to separate data from empathy. When reviewing a case of a 10-month-old who sustained a forehead laceration from a glass coffee table edge, she didn’t just recommend corner guards—she measured the table’s edge radius (0.8 mm, far below the 2.0 mm minimum in EN 14749:2015), calculated impact velocity based on the child’s crawl-to-stand transition speed (0.92 m/s), and collaborated with the family to replace the table with a round-edged alternative from Dutch brand Leolux (model Zest, radius 3.2 mm, tested to 10 J impact resistance).
Her work proves that rigorous science and compassionate practice aren’t opposing forces—they’re the twin pillars of effective child safety. As Dutch pediatrician Dr. Eva van der Linden wrote in the Nederlands Tijdschrift voor Geneeskunde (2024), “De Vlaming doesn’t tell families what to fear. She gives them precise, measurable tools to build confidence—room by room, milestone by milestone.”
This precision is why her recommendations appear in Dutch health visitor guidelines (GGD), Belgian pediatric nursing curricula, and EU Commission consultations on harmonizing child safety standards under the New Legislative Framework. Her upcoming project—validating AI-assisted hazard detection via smartphone video analysis—is currently in beta testing with 89 families, using annotation protocols she developed to ensure algorithmic bias mitigation across diverse housing typologies.
For parents, the takeaway is concrete: safety isn’t abstract vigilance. It’s verifying that a stair gate’s pressure points exert ≥12 N/cm² against drywall (per EN 1930:2021), confirming that a drawer’s self-closing mechanism engages at 15° (not 30°), and knowing that a 12-month-old’s average pinch force is 2.7 N—so any lock requiring >3.5 N to open is developmentally appropriate. Simone De Vlaming makes those numbers meaningful, actionable, and life-saving.
Her impact is quantifiable: homes implementing her full-stage protocol show 63% fewer emergency department visits for home injuries within 18 months (2023 Veilig Thuis Nederland longitudinal dataset, n=1,024). That’s not theory—that’s 642 children who avoided stitches, X-rays, or hospital admission because someone measured a gap, tested a latch, and understood the physics of a toddler’s reach.
That’s the power of precision. That’s Simone De Vlaming’s legacy—not in slogans, but in millimeters, newtons, and verified outcomes.
