ds1's 2.10 and has never had skin problems before. Over the last day or so, however, he's developed a 'belt' of dry, itchy skin around his waist. It started at the front and has now spread round the back, where it is worse - looks red. He's been in a different brand of nappy for the last few days, and the 'belt' appears to be just where the nappy starts - is it likely to be that? His bum doesn't seem to be affected. Would Bepanthen cream be any good for it, as I know we have some? TIA
