Your friend just had a baby and knows that you have been studying memory in childhood. Your friend is concerned that because their child will be non-verbal for so long, it will be impossible to tell if the child is making memories. What would you tell your friend to look for to ease her worries and prove that her child's infant memory is progressing as it should be? What would you suggest as good practices for your friend to use to strengthen memory development as their child gets older (and communicates verbally)?
