My son has been extra drooly for probably three weeks now and all of a sudden yesterday he was Whiney and cranky ALL day long.... Not happy with anything, clingy, and finicky with food. All of which he is never like. He is always extra happy and on the go. I recently moved to one nap a day ( about a week ago) bc that's how my new daycare does it, but I'm wondering if , bc he is extra cranky, he might need that second nap for a few days.... Thoughts?? I was sure, as well as my previous sitter was, that he was ready for one nap... Old it be that he was overly tired from the previous two days that he only got one nap???
