Do you mean as a flicking implement or for actual eating? DD is 2.10 and she can pick stuff up with a fork or spoon (messily) but generally they are used to increase the trajectory she can fling the food!
I was just going to post something very similar to this! My lad is 20 months and I'm having to load up his spoon for him, which he will then quite happily put into his mouth and then hand it back to me for more. I've been trying to encourage him to load it up himself but it just results in tears of frustration and no food eaten. I've been getting paranoid as most people I chat to seem to leave their child to just get on with their meals themselves. But I do wonder what age on average children eat their meals 100% independently.
I've recommended these on here before, but they really helped my DS. He's 21 months now but has been able to eat fairly tidily with a spoon since he was about 14 months, I'm sure due to this cutlery. Apparently the Baby Bjorn set is also good and a little cheaper.
DS has just turned 3 and happily uses a spoon and fork, has done for some time BUT I think this is down to the fact that he is just a trencherman. Food is put in front of him and he eats, it's what he does, it's nothing to do with my parenting.
He will still resort to hands when tired or particularly hungry. Feeding themselves (by hand or implement) is the main thing I think, cutlery is more about manners/cultural expectations.
