My son will be 15 months and he does the same thing with his spoon. He knows what it is for but he likes to put his food on it and then bang it on his tray and smear it around! Give him some time. Boys take a little longer to do things than girls. My son still wants his bottle and didnt really start walking till he was 13 months. My daughter is 4 1/2 and she was walking by 10 months, off the bottle before her first birthday and feeding herself with a spoon at one. Every child is different. Kids learn by playing. Just keep giving him the spoon and some not so messy food like cherrios to practice with and he will get it.
