Mine started abit late. Round about 18 months, but that's because he's so used to us feeding him.
Now that he attends daycare (at 18 months), might be due to peer pressure for other kids his age are feeding themselves, he no longer wants us to feed him. He was making a fuss when I tried to feed him at daycare (on his first day of school). Now he would grab the spoon when no one sees it and try to feed himself and get his school uniform dirty...
