I tore with my daughter (2nd degree) and they offered me stitches and I refused. Bad idea... because it didn't heal properly and it only healed after TWO YEARS!!!! It healed, up to a point, then there was just this open gaping bit right at the end of it. My daughter had her hand on her head, which is likely why I tore.
I tore with my son, but it wasn't as bad and I didn't need stitches. I healed up very well, it took a while but not years like with my daughter. I was in a lot of pain though, I remember at six weeks pp I went to the doctor because I was sure the pain wasn't normal and I thought it was infected, but they had a look and it looked normal. I can't remember exactly when it healed, but it was a few weeks after I went to the doctor.
