We use the Carlson's Lab fish oil in Lemon Flavor made expecially for kids. I started my son on it when he was a year old. I started him out with 1/2 tsp, then gradually increased to 1 tsp/day. I generally give it to him straight from the bottle as he loves lemons anyways. He always asks for his lemon oil at dinner time :). Now the whole family takes it!
