i have to ask why you want to do this. if we are treating an infant for pain or fever i would recommend the tylenol infant drops only. due to the fact that aspirin can increase the risk of reye's syndrome i would not consider chewable 81 milligram baby aspirin. infants and children are not "little adults " so you need to be very careful when it comes to medication.
can you mix bayer chewable 81 milligram baby aspirin and tylenol 80 milligram infant drops?
