sitting up like a big boy

This past week Brendan has mastered sitting up (though he hasn't yet learned how to pull himself into the sitting position).

Sometimes he gets excited and starts to kick his feet which causes him to fall backwards.

He's very good at rolling from back to front but hasn't learned yet how to roll front to back though he keeps trying. Hopefully he will learn this soon because he rolls over in the middle of the night and I have to go in and roll him back.

Now that he can roll, he sleeps on his side or tummy.
