Gavin is all about grabbing these days. Everything he can reach, he grabs, and just about everything he grabs goes into his mouth. Lately, my hair is a favorite target. He just loves sinking his fists into my hair with his vice-like grip. Yank. Ow. He has also started reaching up to my face and touching it. This seems to be a deliberate action - he isn't just accidentally making contact with my face. I think he might sometimes try to hold onto it and bring it to his mouth.
Rolling over is something else he has gotten quite good at recently. If we put him down on his back, within five minutes, he has flipped himself over onto his tummy. He loves being on his tummy. Last night we noticed that he is starting to scoot around in circles while on his belly, and he's starting to look at toys that are out of his reach and you can just tell he is frustrated by not being able to get them.
