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?

I'm a malay n my hubby is a chinese so being stared n questioned by strangers are just regular things for us. when I'm pregnant many people become excited also including the strangers one 🤣 but I will always hold my belly when walk outside so they understand I'm very protective to my baby n don't ever dare to touch my belly as they wishes
