It's never too late. Besides, my kids liked getting spoon fed until they were 3!! However, if I got too busy to feed them, and they were really hungry, they would use a spoon if one was handy out of necessity! I think young children in general enjoy being fed. They have a sense they're growing up, and I think some kids relish being the "baby" as long as they can. You can tie it into the whole comfort food mentality. They get comfort and well being from being attended to by mom, while eating something yummy. What's wrong with that? As they grow up, those moments will be few.
I know these days there's all this pressure on parents to keep kids on development schedules. Further, there's alot of concerns about spoiling kids, or making them develop bad habits. I say phooey. Medical books can not fairly evaluate what your kids need emotionally. I also blame these pressures on daycare centers and early ed programs that want your kids self-sufficient and ready to take care of themselves to cut down on exta work, all in the name of teaching them valuable developmental skills.
I personally don't see a harm in feeding them with a spoon if you yourself don't mind doing it, you have the time, and aren't bothered by comments from others from time to time. Believe me, when they hit the age of reason, and begin to worry about their peers and want to do what they're doing, the spoon feeding will end. Peer pressure starts as early as preschool, and it's a roller coaster ride from there. So enjoy being a mommy a little longer, and don't worry about missing any boats.
If you want, you can always give him toy spoons and dishes and encourage him to care for and feed a stuffed friend, or give him a real spoon, some pastas or mini-counters from a learning store, and let him play/practice using a spoon to get the toys into a cup or bowl. He just might not have the fine motor skills to handle a spoon and is one of those perfectionist types that would rather do it well, or not all. Don't worry. As I already said, he'll eventually feed himself in good time and when he's ready. But until then, you can make spoons something fun and a learning experience. Just always have the spoons handy at meals so he can experiment when he's ready. Also look into toddler friendly spoons that make eating easier. Check out www.onestepahead.com and click on feeding. They have a few different types.
