When I'm out in public, whether I'm grocery shopping or waiting in line at the post office, people ask personal questions about my pregnancy and sometimes even put their hand on my belly. How can I tell them to mind their business without being rude?

If they ask , as long as you can answer just reply it calmly. Also not good to be emotional for preggy mom right! But for put hand on your belly depend on the gender of the person. If women i think it might be consider as they over excitement for other people happiness or maybe they can't have a chance to mom like us. So just enjoy it. If it was a man just give him a punch on face.. hahahaha
