Hey Rach. In my opinion it would be wise to consult your pediatrician. After all it is your child in question so whatever it takes to make her healthy is your obligation.
My sister had huge problems with her baby when she was young and she was spending most of her days just trying to find out what ever she can do to make her child healthy. If she is allergic to something you should ask from your doctor to do all the necessary tests to determine what is in question.
Since it has been long time you have wrote this post you have probably resolved your problems so let us know about the results. Maybe we can help someone else. Thank you in advance.
