Sorry this is long..

When I had my first daughter I never minded people touching my belly. But this one isn't as active and some people in my family feel that it's still okay to just come up and feel all over and try to agitate her to get her to move for them. I tell them that she's not that active especially during the daytime because she's constantly being rocked to sleep(I'm active chasing around a four year old). How do I tell them to stop coming up and "molesting" my stomach without being a bitch. I don't wanna be rude about it but I can't deal with all the touching. My mom is literally the one who has even listened to me comment on not being fond of people just touching me. Idk if it's because I had my first born with a birth plan that was not excecuted or why it's so different this time for me not loving it.. I feel bad because we're a big "babies" family but I can't deal anymore. I hate attending family functions. Thank goodness I'm almost 35 weeks and no more holidays to attend with them but still see them often.. any advice?
