My little 8 month old is going through a lot. Just in the last week he started crawling, pulling himself up on things, and I swear I saw him sign "more" this morning - multiple times.

And in the midst of this, when I put him down for his typical morning nap this morning when he was tired, he is now standing in his crib screeching instead of sleeping.

Could this be a sleep regression? We haven't really been through one before related to napping. What do you do . . . . or not do?
