My ds nursery has just rung to let me know hes had 4 mucky nappies today and his bottom and top of legs are red and have started to blister. They just wanted to let me know coz on the positive side they say hes absolutely fine in himself, has eaten a good lunch, had a good nap and doesn't seem bothered by it at all. They said I don't need to pick him up early coz hes otherwise absolutely fine. What to do? Can't get a docs aptmt coz you have to ring up in the morning. And would the doc just suggest nappy rash cream anyway? Poor ds has obviously eaten something thats disagreed with him. Has anyone any experience of this kind of reaction? Got another 45 mins in work to sit worrying about it.
