18 month old has fever (~99 to 100) for past 2 days, appetite ok. On tylenol, (acetaminophen) what next?

Call you doctor. It's never a good idea to post questions about an acute illness your child is dealing with online because there can be a delay in getting an answer. In general, you're better off discussing these illnesses with your physician's office because sometimes there are other things going on that merit immediate attention.
Keep hydrated. Lots of liquids and keep them comfortable. Liquids are more important than getting in solid food right now. Count number of wet diapers and if decreased this could be a sign of dehydration. Use tylenol (acetaminophen) for discomfort but not to treat the fever, fever isn't dangerous. If your child has a fever (greater than 100.4) for more than 3 days make an appt with your pediatrician for an evaluation.

Taking fluids. It depends mostly on how she looks to you. If she is alert and taking fluids well, wetting her diaper, no breathing difficulties, then symptomatic treatment is advised. Make sure she take more than her usual amount of fluids. Lukewarm baths will help her feel better. You may give Tylenol (acetaminophen) every 4 hours if needed. If she is worsening, trust your instincts and get her evaluated. Hope she feels better. Read more...

Depends. If the child's fever does not truly go down even with meds then she should be seen. Speak with your pharmacist and get the appropriate dosing for children's ibuprofen - this can be helpful. If the child will take fluids that is most important - one can live without food for a day but they must take in plenty of liquids and make urine - if no wet diapers, no tears then she should be seen.
