Re: can I give my 4 month old motrin?
My doc always told me to use the lesser of age or weight, so even if my baby was 12 lbs, if s/he was under 6 mths, I couldn't give motrin. I also give the lower dose of age or weight for tylenol until age 1 after which she said that dosing by weight alone is appropriate.
I also agree with a pp, 101 is not bad. That's your baby's immune system dealing with vaxes/illnesses. I don't medicate until over 103 (unless extremely lethargic), so if tylenol is keeping it under 103, I wouldn't worry. Let the immune system do its job. If you're really worried, call your doc's office, but don't give motrin under 6 mths w/o a physician's advice to do so. It can be VERY hard on an infant's stomach.
