Vitamin - how to give?

[Alesmom]

Started my son on dha fish oil... Recommended dosage is 2ml, which is crazy - two eyedroppers filled to the brim! He's six months old, EBF and we've been sticking the dropper into his mouth and squirting little by little. He doesnt seem to mind, but he thinks its a game and delights over spitting half the liquid back out and laughing. So far I'd say he swallows about 1 ml and spits out the rest.

Is there a better way to do this?

I put his vitamin D directly on my nipple before feeding, but I can't put that much fish oil on.
