@natnatbabygirl,

If you need to give him 3ml and your syringe is only 1.25 then give him two full syringes of the 1.25 first which will be 2.50 ml then give him a half syringe which will be the full 3 ml, or you could just get a regular tablespoon out of your kitchen drawer and pour the medicine in the soon until intend 2/3 full and that's the equivalent of 3ml

You need to give him 3ml? If it's 3 then about 2 1/2 1.25ml doses

I think it'd be in between the 1.25 and .625. I'm not sure though.

post a picture of the syringe , because I'm not following.

@jasalynnsmommy, it says .625

There should be a line at each increment of one half (0.5) milliliter. For 1.25 ml, stop halfway between 1.0 and 1.5 ml.
