What a fun question! The ease at which a parent can get a toddler to use a fork and spoon varies by the child. Remembering that he or she will learn it when ready if you offer it early helps keep things in focus; they won't get to 20 years old and not know how to use a fork. Putting pressure on anything creates a battle and can prolong the process.
Instead, have fun with it and find your inner zen when giving our the fork and spoon - it will be messy, exploratory and they will make it fun for themselves. Always have it sitting there next to them during meals and when there is a success in using it, give LOTS of attention. What are a toddler's goals in life? Two common goals are to explore the unexplored and to get mom and dad's attention because it's so darn fun. If a fork is there, he will try to do what you are doing and when he does, give him a smile and a "you did it!" now and then.
Be sure to not only show the toddler how, give him tactile assistance (hold his hand) to his mouth a few time if he will let you in the beginning if he is struggling. The motion of getting food to mouth on an extension (a fork makes it farther away!) will take some time and practice. At the beginning, he is motor-planning the motion, which basically means that he must think about it in order to accomplish it. As he practices, he will create neuro memories and be able to perform the action automatically. When's the last time you had to focus and really think about getting food to your mouth? Probably a long time ago - now, you can carry on a conversation, pick up something in your other hand, and perform other actions simultaneously. The point is, don't expect success right away because little brains need to develop by DOING.
Another tip is to put favorite foods on the end of the fork. If the reward of getting fork to mouth is a disliked food, kiss cutlery use goodbye. My kids LOVED eating bananas with forks because they loved bananas. Be sure that it's bite sized though because taking a bite out of the food on a fork is pretty difficult for little ones.
Put it out at every meal and make a show of how special getting to use a fork is and don't stress - like anything else with kids, when the pressure is turned on, the toddler might just shut the activity down.
