My Zoe is 3.6 lbs, and she gets 0.3 cc's (right at 1/3 of a cc) of the liquid children's benedryl twice a day for her allergies. Chase is 8 to 9 lbs, and he gets 1/2 of an adult tablet of benedryl. I have given Zoe a quarter of an adult pill when we didn't have the liquid available. I make sure it's actually just a little smaller than 1/4. Hope this helps.

To measure 0.3 cc's you need a very small syringe. The infant benedryl may have a dropper in it that will measure this small, I really don't know, but worth checking.
