It's funny how little people can have such strong preferences. Your baby may grow up to be a very social young lady! Meanwhile, you have a couple of choices as how to handle her demand for social stimulation. You can ignore it and carry on with your business. She may be displeased, bored and irritable for awhile but it doesn't sound like you are ignoring her all day. Of course, if you ARE ignoring her most of the time, that isn't good and should be remedied! You might also put a camera on that nanny to see whether the nanny just leaves the baby in the crib for hours at a time (providing insufficient stimulation) or if she is carrying her around, talking to her, playing with her and so on. If you want to provide a little more social stimulation for the baby and if you are up to it, you can get a pet. Just having a pet wander by, sit near by, make noise and so on may be entertaining enough for the baby (but a lot of work for you - so only do this if you like animals a lot!). A third possibility is to begin to take the baby with you more often because clever babies really do enjoy being out in the world and find the home boring after a short while. You can try the baby groups again because the exposure to other kids will just build up her immunity - talk to your pediatrician about this - but I know of no reason to keep a baby away from other children. Finally, when you are with the baby alone, do try to talk to her about what you are doing ("Mommy is making dinner now...chopping up all the yummy vegetables for the soup....putting all the peels in the garbage can...."). Babies listen carefully to language and although they look like nothing is registering, EVERYTHING is registering! They are little mean, lean, learning machines, soaking up every syllable and utterance. You can put on music as well and just work a little harder at being interesting. I know it sounds like a lot of work, but what can you do when you've got such a smart little baby on your hands?  She's just hungry to learn.  Sarah Chana
