He has an allergy test booked so hopefully we can get some answers from that.
I wonder if it really is heat rash though because he doesn't sweat excessively. I get him to wear loose fitting cotton clothing and he does wear sunscreen. I will talk to his parents about trying another brand. He does get bad eczema as well...
I'm definitely going to try later in the afternoon as well. So far we've only been able to make it outside until 10:30am.
His parents know about it and still bring him out themselves- they don't seem to worried.
