Your baby wakes up in the morning after a solid night’s sleep. You feed her, change her, play with her for a little bit, take her for a little walk outside, then rock her to sleep and put her gently into her crib for her morning nap.

Thirty minutes later she wakes up fussy and irritable, and despite your pleading, bargaining, and offers of riches, refuses to go back to sleep.

After half an hour of trying to put her back down, you finally give in, hoping she’ll be that much more tired when her afternoon nap rolls around, only to have the exact same scenario play out again, and baby is a cranky ball of unhappiness for the rest of the day.

Does this sound familiar?
