Vagina after birth??

Bo

I have read some terrifying shit on here and on the internet about how people’s vaginas don’t go back to normal looks wise and or tightness.. my mom had 3 c section and she asked her boyfriend who has an ex who had 2 kids vaginally and he said there is a huge difference so now I’m freaking out idk what to think ... also readthat people tear and stuff and the doctors sew them up he first time but if your Labia stitches fall out then you just screwed and need plastic surgery to fix it... I do have “lips” so I’m worried
