I had a 2nd degree tear with my first and we waited 6 weeks (the stitches on the outside were gone within a week but at about 5 weeks I found there was some stitching rope and a knot when I wiped (though mine were dissolvable too) ... sorry TMI so I think the stitching went inside a bit and it was just as the stitches inside healed that last little bit came away so I would be careful. It was a bit of a scary experience the first time, but we were just very careful and it was fine.

With DS (my second pregnancy) I had no tearing at all and so we were fine after 6 days. Honestly, not tearing felt like I hadn't even given birth by the next day. It was a completely different experience to DD1.
