Babies with Cows milk allergies

D
For moms that have babies with cows milk allergies... what were their symptoms? My LO has got eczema that just keeps getting worse although I've switched her to soap for eczema, unscented aveeno lotion, eczema cream and laundry detergent that's unscented, dye free etc. She is very gassy, has mucas like diarrhea when she goes, she's starting to get fussy although she's a normally happy baby, she gags a lot and sometimes vomits til she empties her stomach, she's coughs a lot and sometimes she squeakingly gasps for air several times in a row. Does this sound like cows milk allergy or possibly something else? I plan to call her pediatrician in the morning and get her an appointment.
