Is it a blotchy rash or spots ? has he any siblings may have brought an infection in ..could also be an allergy ,or insect bites, does he wear long pants what detergent do you use to wash ?
The red blotches seem to get worse when he is outside...they r on his legs, arms and face..any ideas?
When he is outside does he touch plants or flowers, what is he playing with,any sand do they disappear later?
No he does not touch anything...the interesting thing is the hives r only on skin exposed, he has no hives on upper arms or torso which OS covered by clothes..thoughts
