At what age kids start having food themselves? My son is 2.6 yrs old and he is not eating himself every time!???

Different children do so at different times times. For instance, my elder one started eating on her own when she was about 18 months or so and my younger one did before that. Let your child try to eat and see what happens. Don't take over in between even if you feel you'd do a better job of it. And just in case it doesn't happen, feed your baby..After all, someday I'll surely miss doing so :)
