My son has incredibly sensitive skin and suffers from eczema. When we are introducing solids, like rice cereal, he has a terrible reaction with a diaper rash. Are there certain foods we should try to avoid or could ease into that would have a smaller chance of a negative reaction? Our doctor had suggested waiting up to a week before starting any new foods but we cannot even get past 2 days before his diaper rash is back. Possibly baby oatmeal or skipping store bought food and making my own. I'm willing to do anything as my son really, really wants to eat solids but I don't want him to be miserable with a rash.
