My baby had switched to soy formula per doctors orders but since she has been on it she has had congestion and runny nose. Also some dark poops..sometimes with dark particles in it. Could this be an allergy? I tried to switch back to the formula she was on before but her bowels and congestion did not change.
Hi... cough, cold and nasal congestion are not at all related to the change in food or formula. It is mostly viral or related to seasonal changes. No need to change formula. Regards -
