My toddler has got small red bumps on his stomach area and itches a lot and gets irritated. During winters he faces this issues. Please suggest what to do

A. There can be a possibility that your child is allergic to the material that you are using it could be woolen it could be knitted it could be anything because if it is happening on the stomach also there can be a possibility of energy so please check with your doctor regarding that and as of now you can apply calamine lotion on the body
