Arwen - I will also ask my ped for a prescription when I see him next week just in case. Last summer, my LO (then a 1 year old) got a mozzie bite on his face and I just put on some over the counter creams. He scratched so much that he has a scar on his cheek to this day.
I tried cherubs rub soothing cream on myself before I gave it to my LO, seems to work quite well, and I think all the ingredients are natural, feel safer to use.
