Ok so my boyfriend has a 1 year old little girl and I love her like my own she lives with her birth mother we get to see her every weekend everytime she's here and I hold her my boobs start falling out of my bra and my nipples go hard why? Is it because I want kids? Me and my boyfriend aren't currently trying he doesn't want another kid right now I'd love to start trying since I already know that I struggle with getting pregnant but he's not ready so we're waiting
