If your baby swallowed some fluid at birth this would not still affect her at this stage. From your description here your baby may be allergic. She certainly is allergic to soya milk and probably to cow's milk formulas as well. Try her on a low allergy formula such as NAN HA. Zyrtec is an antihistamine. It is used for allergic babies who start showing these symtoms. The Zyrtec drops are safe but will not clear the mucous from her chest. This is why you need to find a formula that will not aggravate her allergies.
