My little monkey

So the latest is that Seth can push up to a sitting position on his own. Today when he woke up from his nap I went in there and he was sitting up in his crib crying. He stiffens his whole body and screams as loud as he can, it's hilarious... and not. So now I'm sure his sleep will be disrupted by his need to wake up and practice crawling and sitting up. I had to take the mobile down off the crib because he can reach it now. And pretty soon we'll have to lower the mattress since he can almost pull himself up on stuff. Just when my back was starting to feel normal again.
