And yet this is what you first identify with about yourself, just going by your avatar. It’s your belly, it’s up to you to take control. You should resign yourself and get in practice now. You’ll have to do it a lot more over the next eighteen years. “No, I’d rather you didn’t touch me” generally works. I’ve been pregnant three times and I’ve had people approach and ask if they could touch my belly. Saying no is aways an option and I don’t know that anyone ever touched me without my permission. You can see them coming and move away and say “stop” if worst came to worst. And btw,hitting someone is not a “mom instinct”. Where did you get that idea?
