I was operated on the Thursday and back to work Tuesday. As I have a toddler (2, as well as a 5 & 7 year old), I figured I would get more rest in my office job and be less likely to lift toddler. I was fine at work, but tired at night.
I will tell you that I have had a sore back the last week. I tried to lift my 2 year old as little as possible, but could not avoid it (eg-in/out bed/car, nappy changes, etc). I think because I have tried not to use my tummy muscles that I have strained my back.
