Gas, fussiness, spit-up, constipation, eczema and colic are very common formula feeding problems among young children. Marketing research suggests that two out of every three children experience these types of common feeding problems. Intolerance symptoms such as fussiness, gas, spit-up may be due to lactose sensitivity and eczema may be due to cow milk protein sensitivity.2 These symptoms can be a source of frustration for both baby and you. The word that is used to refer to these common issues with baby's digestive system is "intolerance".
