Your Brilliant Baby in Week 15: Evidence of Memory

Let's say your baby falls to sleep easily in her own crib at home, but now you're taking her to childcare where the crib environment is far different. If Baby's routine becomes erratic and she suddenly has difficulty nodding off, be patient: She'll likely need to relearn how to fall asleep in this new context.

Remembering skills in a particular context is true for older children, as well. Just wait until your toddler has to use a public toilet after experiencing only her own potty!
