When they aren't battling over a toy, screaming at the top of their lungs at each other, or knocking each other upside the head with their sippy cups, the girls love to help each other. They like to take things to each other, open doors, find missing toys, dress each other, etc. Sometimes they like to feed each other. Last week, it might have gone a little too far. One of them actually wiped the other one's bottom. Real nice. At least I didn't have to get up to do it. That's a good thing, right? They've offered to do it several times since then, but I've managed to get there in time. We now have a strict no wiping anyone else's bottom unless you are mommy or daddy policy.
