My son is 2 years old and about 23lbs. He possibly took 7ml's of children's ibuprofen and 5ml's of children's tylenol, along with 2.5ml's of Pediacare Cough Medicine in a 4 hour period. I'm at work and my husband isn't sure if our son actually took it all or not. Do we need to take him in to be checked out just in case or is it not something I should worry about?
