I saw you mention that you're a pharmacist, and I have a question if you don't mind giving me your input. My 3 year old son has chicken pox, and DH picked up some kids benadryl at Walgreens. The pharmacist told him that it was ok to give him 1 teaspoon every 6 hours even though it says not for kids under 4. I put a call in to the dr, but who knows when they'll get back to me. Does this sound normal/ok to you? Thanks for any help!
