My belly ever since I had my second daughter who is now 16 months old is just so wierd it's all wrinkly and horrible has any one else experienced this, when I got signed off from the midwife she told me that I needed to go to physio cas my something had not gone down, when mentioned to the docter he said no you don't need that, also that bit in the middle of my belly that sticks out when I breath in is what I used to have when I was pregnant, want my belly back and my belly button still pokes out
