 [ Symptoms ] can you mix bayer chewable 81 mg baby aspirin and tylenol 80 mg infant drops [ Disease ] 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 is 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
