May I know at what age does LO learn to self feed? And what solids at around 15 months onwards?

Mine started trying to eat by himself at about 10 months. He's now 16 months and a lot better and can use spoon and fork as well but it's a process! He's still nowhere near being able to finish a meal by himself and his feeding is more for fun and practice. At this stage, my son eats nearly everything as long as it's a little soft and in small bite sized pieces. I limit high sugar, high salt, spicy foods, nuts and shellfish but he eats pretty much everything else we do.
