How to Know If You Picked the Wrong Formula

Picking the wrong formula can feel like a guessing game, but your baby will give you some telltale signs. Keep an eye out for signs of indigestion, such as excessive gas or fussiness during and after feeds.

If your baby starts refusing to eat or experiences abnormal fussiness, it might be time to reconsider the formula. Funky poops, like diarrhea or constipation, can also be indicators that the formula isn't agreeing with your baby's tummy.

Remember, it's all about finding the right fit for your little one's needs.
