Hey Leash - just found this thread. I have a 6 cm gap hun The physio told me that 1-2 cms is pretty normal and once you have recovered it is important to do gentle exercises to the core muscles to repair it. I have a tube thing that I should wear more often to help my muscles and to support my back which is overcompensating for the fact that I basically has no tummy muscles that work. If they are still separated, make sure you don't use your tummy when sitting up out of bed etc. roll onto your side and push yourself up. Once I get to 6 weeks Im going back for a check up and will see where we go from here because it is so severe. Hope it heals fast for you.
