How do children climb out of cribs?

Insights
Most toddlers climb out of cribs from the corner, but 10% use a side-climbing pattern. This highlights the need to eliminate potential child entrapment hazards from the entire crib perimeter, not just corners.
Area of Science:
- Pediatric safety
- Child development
- Biomechanics
Background:
- Crib safety standards have evolved to address specific entrapment risks.
- Understanding child behavior in cribs is crucial for preventing injuries.
Purpose of the Study:
- To identify and categorize common climbing patterns used by young children to exit cribs.
- To assess the prevalence of side-climbing versus corner-climbing behaviors.
- To inform crib design and safety regulations based on observed child behaviors.
Main Methods:
- Observational study of 48 children aged 16-32 months exiting cribs.
- Each child was observed four times, focusing on their climbing technique and location.
- Children were able to walk independently and were under 35 inches tall.
Main Results:
- Two distinct climbing patterns were identified: corner-climbing and side-climbing.
- 90% of children primarily used a corner-climbing strategy.
- 10% of children exhibited side-climbing behavior in at least one observation.
Conclusions:
- While corner-climbing is most common, the prevalence of side-climbing necessitates safety considerations beyond crib corners.
- Eliminating potential entrapment points along the entire crib perimeter is recommended.
- Updated safety standards should account for diverse child egress behaviors to enhance overall crib safety.
Abstract:
48 children between the ages of 16 and 32 mo. were observed climbing out of a crib. Each child was observed four times climbing out of the crib. All the children were able to walk independently and were less than 35 in. tall. Two different climbing patterns were identified and associated with a location of the climbing event within the crib environment. Most children (90%) climb from a crib by first moving to a corner of the crib and then start climbing from the crib. The remaining 10% of the children used a side-climbing pattern in at least one of the four observations. Crib safety standards have eliminated the most common catch-point, the cornerpost extension from cribs. Since at least 10% of the children climbed over the side of the crib rather than at the corner, any potential catch-points should be eliminated from the complete perimeter of the crib.
