Aleisha,
I have a son who is aout to be 8. When he was starting solids I gave him carrots and he developed a rash and did not seem to like them. I tried them 3 times to see and all 3 times he had the same rash and distatse for them. We ditched them for 6 months like the Dr.'s say, and when we tried them again, he was fine.
My advice is to try one more time in a day or so, if the rash gets worse, put the carrots on hold for a while. I was told it may be the acidity of them, not sure what that meant, but all the pros say to check at least 2x before declaring an allergy. Kids can be allergic to a number of things. Just take it one step at a time.
Good luck!
P.S.
You'd never guess my son hated carrots the first few times. They're his favorite veggie now!
