When your child wakes up in the middle of the night crying with a fever, you need to have the right kind of medication on hand and know the correct dosage that your child requires to start feeling better. In the past, it could be quite confusing because infants' (under age 2) liquid acetaminophen was made in a concentrated form that required a smaller dose, while children's (ages 2 and up) liquid medication was not concentrated and required a whole different level of dosing. If you made a mistake and mixed up the two bottles (so easy to do at 2 a.m. when you are exhausted and not seeing straight), you could easily give too much or too little medication — a potentially dangerous situation. Fortunately, manufacturers of these children's medications realized that this situation was confusing and potentially harmful, and have made voluntary and self-initiated changes to make all of this a lot simpler for parents.
