Okay, I have been giving Frankie a bottle of formula at lunchtime to replace a bf in preparation for me returning to work. She is fine on it and enjoys it no sickness. However since starting her on this she has developed a rash on the side of her face, it looks like little spots. Jonny has eczema and this is exactly how his started but it didn't coincide with him having formula. Could she have an allergy to SMA? If so what can I do? Help please!
