I have a 2.5 year old and 1 yr old. I spoon feed both of them. They both feed themself too but my youngest doesn't get enough in if I don't give her a few spoons full and my oldest is distracted and talking and messing about so I spoon some into him too. Tbh my 2.5 year old just likes it when I feed him. I'm happy to indulge that a little bit.
Why does it bother you? Like I get that it might be a bit odd to you but ultimately what is the worst that could happen? Everyone learns to eat 100% independently eventually. Xxx
