Tummy time doesn't really tire LaRue out, since if she is on the floor she is always on her belly (she will roll over the instant I put her down), but she has fallen asleep quite a few times while on her belly. It's so cute, she'll be playing, then she will pause and play, then she will just lay there, then before I know it she is sleeping.
Today while I was folding clothes, LaRue was laying on the floor next to me, within 10 minutes through a mixture of rolling, scooting, crawling, and swaying she moved about 3 feet to her activity gym. I can not believe how big she is getting, it's just crazy. I miss my little newborn who only fit into preemie clothes. Now she is big and chubby and doing all sorts of things. Whenever I see a little newborn I get all misty eyed, she was that small just such a short time ago.
Chloë didn't have food until she was a year old, she wasn't interested and I wasn't interested in smelly diapers. LaRue is VERY interested, though. Anything I have, she grabs at it. She's taken sips of my water, which always surprises her, sucked on apples, carrots, and grapes, and eats teeny bits of my soy yogurt. Her favorite is the soy yogurt, she will get all excited when I get out and grab for it. Then I'll put just the smallest bit on my spoon and hold it just a little ways away from her mouth to see if she really wants a bite and she will open up her mouth for it. Then after she eats it she gets a big smile and starts kicking excitedly. She doesn't really eat solids right now though, it's more like exploring solids, she's just getting small tastes of things. So we still don't have smelly diapers.
Stacey -- I don't think you should be worried at all about Kate, babies develop at all different rates and the age in which they are able to sit, roll over, walk have no correlation to intelligence or anything like that. She's taking her time to reach these milestones and there is nothing wrong with that. Chloë walked really early, at 7 mo., and at that time she was way ahead of the other kids at walking, but now that she is 4 (and even when she was 1,2, and 3 years of age) her walking at 7 mo. really means nothing. It doesn't mean that she is genius or anything like that, she's a bright 4 year old, just like her friend who walked at 12 mo. is a bright 4 year old. And her friend who walked at 12 mo. is a really advanced reader. But him reading at 3 y.o. doesn't mean that he is a genius either, it just means that he started to read at 3 y.o. I actually taught myself to read when I was 3 and although I am smart and got straight a's at school, it doesn't mean that I'm more brilliant than a person who started to read at 5 years old. Supposedly Einstein didn't even speak until he was 4 y.o. and he was definitely more brilliant than I am. So this is my long-winded way to say that there is nothing to worry about
