Did your kids have a wakeful period when they learned to go from tummy to sitting? DS has been fighting naps and waking up throughout the night. Every time I look at the monitor when I hear him awake, he's always sitting and playing. Then get's frustrated or tired and can't seem to go back to sleep, even though he can get back to his tummy. It's like his new trick and he can't stop doing it. Any advice?

Re: less sleep when learned to go from tummy to sitting?
You can expect less sleep whenever a new skill of any kind is learned. Hang in there!
