Baby food



Rice cereal


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.


Hi Sarah,

Sorry to hear that. Is rice cereal the only food you've tried? There are a handful of foods, as you probably already know, that may be linked to baby eczema, but these are not even the typical first foods you'd give a baby (like soy, fish, peanuts, etc.). Have you tried fruits and/or veggies? While food can certainly be a trigger for baby eczema, it is not necessarily the only cause. Was he experiencing this diaper rash before starting solids as well?


We started with rice cereal but have also done bananas and avocado. I thought he was having a reaction to avocado before but now think it could have just been the rice cereal. I'm interested in starting him on more veggies like spinach and sweet potatoes. I will be making all of my baby food (more for cost benefit).


His diaper rash only started once we started him on solids and went away once we stopped. We also recently switched him to formula from breastmilk but he did not have a negative reaction at all.


Keep a log of any new foods tried and any potential reactions and of course stop as soon as you see a negative reaction, as it sounds like you've been doing. As painful as diaper rash looks (and likely is for the little one), it doesn't necessarily mean it is a food your baby cannot tolerate going forward. When babies start eating solid foods, the frequency and content of their bowel movements changes, which can make diaper rash more likely.
