Girls, how's your tummy after childbirth? I have this feeling like my belly is hanging ? How do you get rid of it? Before pregnancy, I didn't even have a belly? By the way, right after childbirth, should we start tightening it? I did nothing, as my mom said that it will go away on its own, and here it's been 3 months since childbirth, but my belly is soft and still hangs ? Help me with advice, who dealt with it like this?
