abdominal separation (diastasis recti)

Mandie

anyone knowledgeable on this? I have a 3 year old, 2 year old, and a 5 month old, and my abdominal muscles haven't healed since my first baby. They've been completely separated for so long! I don't know how to make them heal! And now I just read that sit ups makes it worse! (And that's what I've been doing!) How long does it take to heal? What exercises are safe to do with a separated abdomin?
