Naptime or playtime?

Baby A was very tired today... so tired that I put him down for his afternoon nap at noon instead of 2. As usual, I heard him talking to himself for a little while. Then it was pretty quiet so I assumed he fell asleep.

Nope.

I looked over at his bed and this is what I saw:

That was the first time he has decided to stand up in his bed. We will be moving his mattress down on his crib this evening!

And the standing was followed by this silliness...






He also just learned how to get to a sitting position from lying down.
This is a month of many firsts for our little big man.
