My friend's 5,5 month old baby doesn't eat or sleep, cries all the time, has eczema , used so many creams but nothing helps, is lactose intolerant?

Needs care: The baby needs to be seen by a pediatrician for allergy testing and better care for eczema. Lactose intolerance is not an allergy. It is an inability to break down the milk sugar, lactose, leading to diarrhea.More likely is a protein intolerance or allergy. The baby may need a hypoallergenic or amino acid based formula. Severe eczema can be worsened by bacterial colonization of the skin.
