have you considered a playgroup or something similar at all? Also gives you a great opportunity to have another outlet for socialising too - not sure if they have anything like that in the States? I think your family are well intentioned and only are thinking of the best for her, but if you feel like you're being pressured to do it then maybe wait a while and see how she goes with her clingyiness etc kwim? You may even want to look into short term care for a few hours once a week or something as your pg progresses to give you a bit of time out and to help you get things down without a little one underfoot.
