I don't know what happened to my baby

I woke up last Friday and he was SIX MONTHS OLD!

How do they grow up so fast? He must do it while I'm at school. He promised me he wasn't going to get any bigger, but he just keeps getting bigger...okay, so his promise was more like a gurgle, but still he's getting big way to fast. Its as if he knows he's my last baby and he doesn't want me to enjoy the baby part for much longer
He is developing greatly though. He loves his squash and bananas...he's not too fond of peas though (I can't blame him) and he loves cereal (both rice and oatmeal) and he sure does a good job eating. You just can't get the food in his mouth fast enough sometimes. He'll even take the spoon away from you and try to feed himself
He can roll over both ways (back to belly and belly to back) and he seems to being scooting (not crawling yet) but he never does it when you look. We bought him the Tummy Time by Playskool and he'll be playing with it and I turn my back for one second and he's turned himself around or scooted to another area of his playmat. Only when I'm not looking though
He should be getting his first tooth soon. You can kinda see it like right under the gums. He's been teething REALLY hard these past couple of weeks, biting down hard on anything he can get in his mouth. He's had a bit of dirreah (sp?) this past week and MIL said when DH got his first tooth he went through the same thing a couple of weeks before the tooth finally showed up. My mom says I got my first tooth at six months and DD got hers at 6 months also, so his should be here soon.
We just had our Christmas pictures made last weekend, so when I get those in I'll post them. He is soooooo cute! We put him in one of those baby suits. We're looking foward to his first Christmas.
