DS is refusing to nap. He'll play in his crib (today for 2.5 hours) and be calm and happy but refuses to fall asleep. I know he's tired. He rubs his eyes, he's cranky and tantrums but will not sleep.
Is this common when children learn new physical skills?
DS just started crawling about 2 weeks ago and is starting to explore more (he's finally crawling out of the living room). Could it just be the explosion of physical skills (in the past 12 weeks he's learned to sit, then army crawl and now crawl on his hands and knees).
Last night he slept from 10-7 with 1 wake up so it's not like he's sleeping 14 hours a night.
Re: Why won't he nap?
Whenever Liam was picking up new skills he would go through an anti-sleep phase. I think their brains and bodies are just so active trying to process everything that is going on that it's hard for them to settle down and shut everything off.
I would just continue with your normal naptime routine for a while and see what happens. I think he will sleep eventually once he starts mastering all of these new skills and they become more "old news".
