DD1is 2.8 she can use a fork and spoon, although not together.
If left to it she'll use her fingers, for everything inc yogurt, mash even weetabix.
She's a bit of a fuss pot at the best of times, so I don't make a song and dance about it - however, my DP does and when he is at home to eat with us, he asks her to use her cutlery approx 10 times per meal! She tries but either uses her finger to push the food onto her spoon or picks it up and puts it on her fork/spoon 
Cue lecture about table manners from DP.
At what age did your DC start using their cutlery with confidence?
