We have genetic high cholesterol in my family, so I would consider it when he's older, but not as a toddler. As someone who just watched my 2yo ds have doctors spend a very traumatic 20 minutes trying to get blood from him yesterday (he has an "undertermined virus!") I would not subject him to that again till he's much older. It's a horrible thing to have to hold your child down while someone inflicts pain on him!
