My Lo is 9 months old and today had a large amount or urate crystals in nappy. Lo has dropped down from 3 bottles to 2 bottles the past few days but has increased water/juice intake to co inside with this. No other symptoms and seems fine In self. I am worried as someone I know had the same issue with their Lo a while back and was sent home by GP saying it was mormal but their Lo had renal failure. I will wait until Monday and if still there go to doctor but just wondering is there anything I should be doing?
