I have to admit it feels wierd to have people touch my belly - even my mom, but I don't mind sharing the experience. THere was a sweet lady at my old job that would always touch my belly when I was pregnant with DS.
It was awkward, but she came from such a good place that I didn't mind.
Ok, now I am signing off to go take a nap in my car. lol!
No strangers have ever really asked me, I don't think. But I don't mind at all. If it was a stranger, and they asked my permission, I'd be totally fine with it!
I'm fine when people ask first. Or if it's a friend/family member I'm very close to (like a BFF from school or an aunt), then I don't care if they just go for it. My DH's grandfather, who is very touchy-feely anyway, walked right up to me and rubbed my belly when I was pregnant with my first and barely showing and it totally weirded me out LOL but I've since just come to expect that from him.
