Preston turned 4 months old on the 1st of this month - why is time flying by so fast?!?! 4 months has been the most fun month yet, but I'm sure I'll probably say that about every month/year from here on out!
He also *really* wants to sit up! And he can actually do it for a few seconds before toppling over. We are using the Bumbo quite a bit and I just ordered him a high chair, so that should make him happy since the recline on his bouncy chair is starting to frustrate him.
I think the sleep regression has really hit naps harder than night time sleep - P just does NOT want to takes naps anymore. He just hates to miss out on anything during the day while he's at school, so sometimes I pick him up from daycare and his teachers give me his nap report and there's three 15 minutes naps on it. Yeah, not good! Usually on weekends, I can get a few pretty good naps out of him - I think because it's quiet and there's not as much stimulation at home.
We also just recently ended the swaddle addiction and baby boy no longer requires being wrapped up like a burrito! He's sleeping arms free in just a sleep sack, which is awesome.
