It could become a problem if he ever has to stay with a friend or be boarded while you're on vacation. Do not expect other people to be willing to spoon feed your baby.
If I were you I would stop the spoon feeding cold turkey and get him back to eating on his own. He may act finickey for a day or two and not eat his dinner, but once he gets hungry enough I'm sure he will have no problem digging into his own bowl. Chester gets finicky sometimes, but if he doesn't eat from his bowl within 20 minutes I take it up, put it in the fridge and give it to him the next day. By the next day he is really hungry and won't be so finicky.
I know you love your baby, but spoon feeding is a bit too much pampering.
