Nah BG, I'm sure, since she is your mother, she understands your "space" needs.

Totally different with kids I agree - make them feel special and included and stuff

FWIW - I hated everyone touching my belly on my first pregnancy - and then because nobody is ever excited for you on your second one - couldn't wait for people to ask to touch it!!! I even offered my mum a feel and she rejected me.. lol
