I had some small tears/grazing with my last DS...and I was feeling great straight after the birth and had minimal swelling/no pain etc. So about 2 weeks later I was ready to go...but we discovered my body wasn't DS was 9lbs9.5oz and the doc and my physio said his size would have just stretched the muscles right out and they hadn't had time to retract properly and recover - it was like a cavern in there and not enjoyable for either of us. However, within another 2 or 3 weeks we were fine, and apparently the muscles were...tighter...than usual, too. Which I was rather relieved about - I was beginning to think I was stretched beyond repair! LOL
