My daughter was always making popping sounds. When she was born her right knee still popped all the time. This baby I've heard nothing until a very loud pop today. It's pretty fascinating.

Omg thank you so much for responding. I started freaking out!!!! Called the hospital and the doctor on call said I may have gas. I told him I know the sound and difference and hung up lol. Yes, there is lack of space in my belly from my last ultrasound. Now it all makes sense. My poor baby is trying to make room.

Yes, all of my babies do this when they start running out of room their joints will pop as they roll and move. It grosses me out every time but completely normal!
