Hi there, DD is 3. Has been complaining of a sore bottom today, it looks quite red so have put some sudocrem on. Complained at bedtime still sore, I had another good look and there was what looked like ( I imagine?!) a little worm about an inch long on the red sore bit around her bottom (it was totally out of her bottom). She insists it is sore, not itchy and I am now doubting myself wondering if it was a worm or if it was just a thread or something? Would worms cause a sore bottom and would they be totally out of her bottom? any ideas...thanks!
