After seeing a picture in a pregnancy book the mw gave me, I was shocked at the size of the baby's head compared to the vagina. I know that they're special muscles etc etc but I suppose what I'm wanting to know is does it go back to normal or will it be slightly different? This is my first and it's silly but it is worrying me, especially as I've heard other womens partners making jokes about it. I tried to ask my mum but she just killed herself laughing.
