has anyone given their child baby cereal "early"(i.e. 2 months) and regretted it, or had it negatively effect their baby?
I didn't with my kids. Generally a two month old is not developmentally ready to try foods. It's not really helpful.
Yes, I did with my first. It was fine at first but then after a month he started having severe constipation and then he got eczema. The eczema has been with him ever since. With my other kids I did the research and skipped rice cereal all together and they are much healthier and happier.
I've read way too much on the bad effects of cereal so we're skipping it completely with Charlie. We didn't start any other solids until the 6 month mark.
