Stitches after vaginal birth

Lia

Gave birth on the 24/11 I got stitches 4 different places. I wasn’t told what degree tears they were. Unfortunately, I’m not able to rest as much as I’m supposed to. I’m a single mom of my newborn and my 23 month old son. Whenever I sit, I feel only one of the stitches pinch me. The others doesn’t hurt unless I open my legs, accidentally sit on something hard or when I’m wiping my bum. Is this normal? When does it stop hurting? I do sitz bath as instructed by my midwife.
