I sat up on my own today! It was the first time I stayed put when Mommy let go of me! Of course she didn't go far...after about a minute my muscles got really tired and I started to tip over. Sitting up is so much fun!
I've also been making progress towards crawling during tummy time. I've been working hard at pushing myself up on my knees and elbows and rocking a little. When I really focus I can scoot myself backwards a little bit :-) I don't care too much about rolling over though. When I'm on my tummy I just work on pushing myself up and then get frustrated when I get worn out. I prefer to just lay on my back and laugh out loud at the funny faces Mommy makes at me!
