My 6 yr old is on a 30 day trial of penicillin. It has been 4 days and he a tally came home in a much calmer mood today. I gave him a fish oil supplement, penicillin , and a third of an adult dose of probiotic( which he's never had before) within 30 min to a hour he became hyper, silly and defiant. Could any of these be a trigger?
