DD is 8 months and has rarely suffered from a sore bum until recently. Before the most she'd have was a little bit of redness that I would coat with sudocrem and would disappear by the next nappy change. This past week or so I've noticed she's got two small sore patches on her bum. I've been coating them with a thick layer of sudocrem at each nappy change but they don't seem to be going away, and first thing in the morning after she's been in her nappy all night they seem to be getting worse. MIL said that when SIL was a baby she had a really sore bum while she was teething so I wondered if that had anything to do with it, although she's been showing signs of teething since she was 3 months old and we've no teeth yet.
Is there anything over the counter that would do a better job, or should I take her to the gp? I don't want to waste doctors time over nappy rash but if there's something that needs to be prescribed then fair enough.
