My breastfed 5 day old ds has lots of dirty nappies (10+ a day?) Firstly is this normal and secondly what do I do about his sore bottom?! Am only using cotton wool and water and am changing him as soon as it needs doing (very noisy so there's no mistaking when it needs doing!) but he has a little bit of nappy rash. What (if anything) should I put on it? I have very sensitive skin as does ds1 so I know I will need to ber very careful.
