DS has been drinking Gatorade for YEARS. Just recently (over the last 6 weeks or so) he has started developing a rash on his upper lip when he drinks it. At first I thought it was just the "kool aide" smile they get from drinking something that will stain their skin, but upon closer inspection it is a rash.
It only happens with Gatorade, and tonight it is the worst ever. It happens immediately. As soon as it touches his upper lip.
Has anyone else experienced this or have any ideas as to why it is happening?
Thanks in advance...
