Ultimately it's up to you but I'd just explain to them "mommy is hungry too and I need my hands to eat my food. you are going to use your own hands to eat now too." Or whatever
Plop the food in front of them and be done with it.
I always say my job is to put the food in front of them, their job is to put it in their mouth.
Toddlers are grazers. They can go days eating very little and then one day they will just shove every bit of food you offer in their little mouth
I'd say hand the spoon to them and just let it be.
Easier said then done of course.
