We don't have DS on much of a schedule. He wakes up when we do, is fed when hungry, naps when he's tired. DH is a WAHD, so he just goes with the flow with DS's needs.

I have a bedtime routine for him where I read a book, turn out the light and nurse him before I put him in his crib. It's worked really well for a while but for the past few nights he's started crying when I turn out the light. I'm with him and I rub his back, hold him, etc. I can tell he's about to fall asleep because his eyes are always closed while he's crying and he's trying to suck his thumb (he always does that when he's about to sleep). Up until a few nights ago, he's never cried when it's bedtime.

It's like he's fighting sleep these days.. is that normal?
