Tips:
Try putting food in different small pots, so they help themselves.
Do not be fussy about them putting things on plate and eating from there, spoon in each pot and if they want to eat just all the peas, then let them. No pots use a small drinking glass.
Use air tight boxes for leftovers, reuse in next meal / adults meals.
Small quantities - look at size of their fist, stomach is about that size, it is not that big.
Cut things into shapes - some like squares, some triangles, some will change their mind constantly!
