DS1 used to take 2 1.5-hour naps and still sleep 10 hours at night.

Even since he starts walking (he went from barely standing to running in a week), he refuses to nap and sleep at night. It sometimes takes more than 1 hour for him to fall asleep at night. While laying in bed, he signs milk every 5 mintues. Clearly, he is not hungry. We cosleep, so I cannot just leave him by himself.

I know a lot of you have children who don't sleep well. Anyone has similar experience?
