My dd is 6m & has been on og oatmeal for 1 month, i started to introduce other solids- prunes, advacado, banana's & apples. I make all her food & it's all organic. I always wait 3 days to introduce something new. The last new food was apples & all of sudden she has a terrible diaper rash. She's never had a rash before & I'm very diligent about changing her. Could this be from the apples?? What should I do? Stop the apples, or will this pass once her bodies use to the change? She doesn't seem to mind, but it looks awful!
