at 9mo., we were moving, so dd was VERY busy unpacking boxes and getting into absolutely everything! Other than that, she is definitely not a home body and since about 4mo of age, needs more activity than mom. We go somewhere everyday, even if it's to Costco to eat samples, she just needs to do something new. At 9 mo, she liked to swing in the park, read books, and get into everything. That's about the time that I made her a cupboard in the kitchen for her to play in, and she loved to listen to (and watch) music. I think at first I tried too hard to keep her entertained with baby things, when really, she is interested in what I'm doing, so I just try to involve her in daily things.
