No need to return: The concentration found in childrens Acetaminophen can most certainly be used in infants. The infants concentration is actually currently being phased off of the market. The amount to be given is weight dependent. Acetaminophen is dosed at 15mg/kg/ dose. So, i would need to know childs weight. A 20 lb baby would get 4 ml every 4- 6 hours.

Fine to use : As long as the proper dosage per weight is given, it doesn't matter what preparation you use. The infant drop preparation is more concentrated & helps moms who struggle with kids to get the medicine down. Verify the concentration of the product you bought. Most have 160mg/5ml. The average 9m girl @ ~19lb would get 1/2 tsp every 6-8h.
