Hi everyone, FTM here. I've done some research and read that it is relatively normal, but I just wanted to ask other mums for my own peace of mind. 
My little boy is one week old today, to my surprise his cord fell off Monday - but midwife came on Monday and said that it can never come off 'too early'. However I noticed yesterday that there was some dried blood on his nappy, and again today there is some on his vest. Not much blood at all, I just didn't want to risk it being infected.
