I'm 8 months and mine still has a little padding. I was not overweight before baby but I'm carrying small. He's very much inside and my organs made lots of room. You can tell it's really hard underneath and when he moves I can see it from the outside
I'm almost 6 months and my tummy is pretty solid. It still has a little squish to it but not much and I was very small before I got pregnant so its not fat lol
It's different for everyone! Mine was probably 7-8 months!
