I sure did. I gave my son oatmeal then barley cereal at 6 months and he vomited like crazy, had a terrible reaction, diarrhea, cold sweats, lethargic. He wouldn't even try the rice cereal, so I didn't feed him anything for another month. After awhile I realized I had to feed him solids eventually! So I started with the basics. Sweet potato, squash, pear. Now the doctor tells me to stay away from any processed foods, any jarred baby food that is a mixture of things instead of just one or two simple ingredients. Bread is just hard because I found out he also cannot have wheat, eggs, and of course milk.
I did feed him a lot of formula only up until about 7 or 8 months. Then I started the purees again, making sure it was the simple stuff. Remember to let them play with the food too, like get apple slices, safe finger foods, etc. I wish I had with my son as now he is 12 months and won't pick up anything and put it to his mouth and he can't stand anything with texture. He is slowly trying bread, I found a good recipe, will lick it and put it in his mouth, gags every now and then, but he is sloooowwwly getting it.
Though it is tempting to keep them on what we know works, they gotta grow up sometime and we don't want to cause more problems in the future by keeping them back food-wise. It might be good to keep a food diary so you know what reactions he gets with what food. How old is your little man anyway?
