Bringing your new baby home is a delightful experience but stress can arise when your baby gets fussy. Having a baby in tears can be exhausting and be overwhelming for a new parent. Crying newborns are often dealing with digestive distress or food allergies. There is a difference between a milk allergy and a milk intolerance. A milk intolerance is when your baby is having trouble digesting the lactose in the formula or breastmilk. This is common in newborns as their digestive system isn’t fully developed yet.
