Can anyone help? DD is 6 months old and she has started to smell...well I mean her wee smells toxic. I frequently change her nappy - every 2 hours but the smell seems to be with her all the time. I had one lady comment about how DD needed a change but I'd just changed her...was really emabarrassed about this. I only use baby wipes to clean her so haven't changed anything in that respect. Was suggested that maybe she needs to drink more water. Any suggestions?
