Recently my 2.5yo toddler keeps scratching his tummy till it bled. Not anywhere else, just the tummy. It's been 2weeks+ and tried nappy rash cream, ruyi oil and moisturizer, moisturizing bath foam. We think it's the school floors since he likes to lie belly down. But I'm al so worried it may be other reasons. Any mums had experience on this? Any home remedies I can try, esp to stop the scratching? I do not want to go to pd and end up with steroid creams...
