Interesting, I've had a number of people, strangers, tell me they wish they had twins. "I always wanted twins." I don't question that desire at all. My thought following such a comment is: you have no clue how busy having multiples is. It isn't merely times two of whatever work is involved for one child. Trust me. No? Why don't you come over to the house for a day. . .
Christian is, for the most part, at this time, is more predictable and easier of the two. He's slowly getting the hang of sticking stuff in his mouth. But, when I first introduced baby food, he was so angry (he can scream quite LOUD) I wasn't getting food into him fast enough. I think he was so pleased he had the swallowing reflex down from the start. When he's tired or wants to nurse, he also bellows quite loudly.
Christine has been pretty adept at army crawling at 8 1/2 mos. She's been trying to figure out how to open cabinets (thank goodness for latches). And, when she has a moment, she's busy opening the trash can! She'll probably be the first to play with toilet water when no one's looking.
She's pretty good at self-feeding finger foods. She also gets into trouble taking little tidbits of whatever she finds on her floor adventures into her mouth. Christine, for several weeks, has also been able to call out "Mama," when she knows I'm around. If she's crawling and wants me to pick her up, she says "Mama" and starts flying (picking up her arms and her legs).
I'm not complaining. I love my twins. But, they keep me on my toes. And I will be very busy. Until I die.
