I had the worst luck with my two year old daughter. As a baby, she was the one who was constantly sick. It made it very rough on me, because at such a young age there isn't much you can do for them when they have a fever. It wasn't until she was about 4-5 months old that I discovered this "Pediacare infant fever reducer and pain reliever drops" I believe the age is for 0 months to 36 months old. So it is gentle enough for newborn babies. That is what really put my mind at ease, if moms use it on newborns, my baby can definitely handle it. It came with it's own sterile syringe and measuring cup. Very distinct directions and even a number to a hot line if I wanted more information about the product. My daughter had a cold and was carrying a high fever when we used this on her. Within an hour she was not near as fussy, and her fever was just about gone! This was all I would use on her as a baby and to this day, I still keep it on hand. I definitely recommend this to all the moms out there. It works well and it is a very mild and gentle medication for all ages.
