I have a 3 month old in she is sick i no i am post a give her 1/4 of tylenol (acetaminophen). but how much can i give her in a day like how many doses. she is 9oz?

See dosing: http://www.getreliefresponsibly.com/acetaminophen-dosage/infants-and-children this website is very helpful for dosing. Why does she need tylenol? Does she have a fever? At three months it is wisest to have her seen before giving any medication....Especially when unsure of the dose. Surely she weighs more than 9 oz? 9 kilogtrams perhaps? Tylenol can be given every 4- 6 hours . Have her seen first.
