I had no idea older LO's could get cradle cap, but I just noticed my 2.5 year olds head is full of it! Is it basically just from dryness? Should I try a shampoo change? We've been using Babyganics, but I'm not sure if that's been causing it or not. How can I get rid of it quickly? I know you can use baby oil, but that's just so greasy and messy...
