Shaken baby syndrome (SBS) triggers negative short- and long-term outcomes. In France, registered childminders are the principal source of daycare. They may encounter SBS imparted by caregivers or simply excessive infant crying. The aim of the study was to explore childminder knowledge on SBS, the source of information, the responses to infant crying, how childminders perceived their roles in terms of caregiver SBS prevention, and the factors associated with a good knowledge of SBS.

The participants were registered childminders working in the French department of Gironde who had email accounts. This observational study employed an anonymous online questionnaire distributed by the maternal and child health services unit of the Gironde department over 5 weeks from 16 September 2021. Data on childminder characteristics, knowledge on SBS, responses to infant crying, and perceptions of their roles in SBS prevention were collected. The knowledge score ranged from 0 (all wrong answers) to 30 (all correct answers).

A total of 779 registered childminders participated; 43.9 % had learnt about SBS during their initial training and 75 % before (other training) or after initial training. The median knowledge score was 19/30 (interquartile range [16; 21]). A higher educational level, previous other professional experience, training on SBS, and responsibility for few children were associated with higher scores. Ten reported that they did not advise caregivers who complained of infant crying.

Childminders require training on SBS and SBS prevention.
