Hello, I am the dad of a 15 month old boy who has a great appetite and eats everything and anything that is put in front of him, however im thinking its time to start introducing him to eating utensils i.e spoon and fork. At the moment i am spoon feeding him with no problems and occasionally he will have finger foods that he loves getting dirty and using his hands on to feed himself. At every feed time i place a spoon next to his bowl so that he can associate the spoon with feeding times, however he either just picks it up and throws it on the ground, teeths on it or just ignores it. I understand that he is still young but have seen other babies younger then him using a spoon and i dont want him to just get used to me feeding him. At what age did everyone else try and any tips would be appreciated. I also understand that its going to be a messy few months teaching him. Thanks all.
