Your baby is not an allergic baby and all tests for allergy are negative. She probably has a lactose intolerance but cannot tolerate soya formulas. You will need to start her on a lactose free formula such as NAN LF or S26 LF. The Novalac AC contains lactose and in any case is making your baby very constipated so it must be stopped immediately.Please let me know how your baby gets on once she is on the LF formula.
