Allergies or dryskin


My son’s pediatrician is confident that my son doesn’t have allergies but instead dry skin/eczema. However his eye is always red/itchy and will even crust underneath. He always has a full body rash on his trunk that is itchy. I just feel terrible he is so uncomfortable. We are usually all the the things the doctor recommended but am wondering if any other moms out there had there babies deal with this? I just deep down think it could be allergies
