In the last week my dd (10 mo.) has developed a rash around her mouth. It comes and goes, sometimes more severe, seemingly after meals. My guess is that it must be a food allergy (or intolerance). She has always had some mild eczema on her stomach, but never even really enough to warrant treatment of any kind other than a bit of cream. It doesn't seem to bother her... more like a few dry patches. She rarely spit up when younger, but in the last month or two has started to spit up/vomit occasionally (every 2-3 days?) about 1/2 hr to 2 hrs after bf-ing. (Pardon the info, but it doesn't smell like sweet baby spit-up, but more like acidic vomit). She does not usually have firm stools. I'm not sure if that's normal for a 10 m.o. - can't remember those days w/ my now-three-year-old. I've never had allergies and my son hasn't either. I did ask the ped. about the possibility of allergies when I took her in for the tummy dry patches, and she dismissed the idea. Would MSPI develop this late?
So now I have no clue how to proceed. From the bit of reading I've done online, I understand it could be an intolerance to milk/soy protein but may also be other things (e.g., tomato, fruit, bread, etc.) in her diet and possibly through bf-ing. Is the first step a trip to the pediatrician? An allergy specialist? Another specialist? Or is it wise to first try eliminating certain foods from her diet? Would I then also eliminate foods from my diet since she's nursing 4x/day? Which foods?
Thanks for any guidance or suggestions. The whole thing is a bit intimidating to me at this point.
