a 9 pound infant is likely a very new baby. for a child of this age and size i would first check with the child’s pediatrician. acetaminophen is labeled for over-the-counter use in children 2 years of age or older. parents trying to treat a child this age should really talk to the pediatrician first. if the pediatrician says it is ok to give the child acetaminophen then we do need to consider the child’s weight in order to dose the product appropriately. tylenol infant’s and children’s products have recently been reformulated so that they now contain the same concentration of acetaminophen 160 mg/5 ml. however if you have an older package of tylenol (acetaminophen) at home then it may have a different strength. it is very important to know the product you are working with so that we give your child the correct amount. talk with your pediatrician or local pharmacist who can tell you the correct dose for your child based on weight and the product you have on hand. you will need to measure the correct amount with the dropper that is packaged with the product. your local pharmacist can help you use the device that you have so that the appropriate amount of medication is given to your child.
