Does Acquiring New Skills Affect Sleep?

yes, yes, yes... this is normal. your son is probably eager to practice all of his new skills. and combine that with teething and you could be in for some long nights! if you think it's the teething, try giving tylenol at bedtime instead of waiting until he wakes up crying... it might help him get a better night's sleep. also, sleep patterns continue to change all the time with babies and toddlers, especially during that transition period from baby to toddler around 12 months. our son actually finally started sleeping better around that time. before around 11 months, he never napped for more than 30 minutes. it was crazy.

Yep. And sometimes they pull up and don't know how to get back down. It passes, though and once they are more mobile and mastered the skill, they seem to sleep better as they are doing it all the time when they are awake. Lol.

Yes yes yes it does. When babies are learning big things they think about them and work on them day and night - even in their sleep sometimes! It's normal. It will pass soon. Hang in there! I remember finding our son on his hands and knees or even standing in his crib, half asleep, in the middle of the night.

I don't think the new skills per say are causing the sleep issue, but the fact that he is using more muscles that he has in the past he is most likely achey. So the tylenol is working to ease his aches. Once he's used standing etc. it won't be an issue.
