We mix medicines with a bit of water or milk in a cup and give him a straw, he gulps it all down, worst case we add a dash of cordial to the water or a small amount of Milo to the milk, but make sure he sees us add it and make a big deal of it like 'Oooo, yummy!' etc and there's never a drama.. He doesn't mind the taste of the nurofen and will suck that out of the syringe himself but all others we have to mix..
