I still have separation 12 mths on from the twins. Although in my case it has been pretty hard to avoid lifting heavy objects - 2 babies now weighing a total of 20kg's, twin pram, 2 1/2 yr old toddler.

I wore recovery shorts for 6 mths after the twins were born and it helped to support my stomach and back but didn't help with repairing the separation. For me I think surgery is the only way my stomach muscles will get put back together, but I was pretty much 'ripped in half' carrying my boys as I carried all to the front and was measuring in comparison to 52 weeks pregnant for a singleton.

Some people are lucky and can get core strength back pretty well, but not me unfortnately...
