We have a new baby – This formula has been amazing! Really struggled with bub having A LOT of wind following bottles, we changed bottles and tears multiple times until we realised it was the formula! The first bottle of Novalac colic and it was like we had a new baby, no screaming or squirming in pain and no wind at all! Initially had a little bit of constipation while her tummy got used to it but cleared upon about a week, we just used infants friend in the mean time which worked a treat!
