Well, the first time M really was into a boy was when she could not take her eyes of a drummer at a local festival. But usually she totally ignores other babies, or just observes them. She occasionally tries to get in on something big kids are doing and often wants toys from other kids, but she doesn't really ever play with other babies. Well, we went to this indoor play place with a baby area, and she met a 10 month-old who was built like the hulk and was walking and picking up big blocks. They hugged, chased each other, and played peek-a-boo. I was shocked. We were in another town and so perhaps they'll never meet again. I hope I didn't make a mistake by not finding out how to contact this baby. There was definite chemistry.
