I genuinely believe that kids eat what they need. BUT they pick up very quickly when it stresses their parents. (been there done that!)
I now care for my niece and nephew. DNeph is a horror with food. PFB etc. DNiec is a hoover.
having had a hideous time with picky ds who took forever to eat...driving me insane with fury/anxiety
DNeph get total indifference from from me. Dont want it fine. Dont eat it. Its on the plate? dont care, don't eat it.
But what I do do with him is involve him in cooking every meal.
That really helps. "see what XXX cooked today?"
Dneph is a grazer. Dneice is a scoffer.
Dneph is a stressy bunny. Dniece is not.
My general rule is to give em sommut he like with summat he aint sure about and to just shrug if he doesnt want it.
Its not too hard to mix it all up for them both.
Irs hard when its your child.
Its not hard when they are not.
This is the lesson I have learnt.
And I do have a ds with serious sensory issues re food!
I just cook him what he like with stuff extra. I have learnt he eats a whole lot more at school! as long as I cover cars/protien and veg I am happyl.
Also, always remember, an small childs portion is three of their handfuls...often a huge amount less tha we serve them.
last tip, I promise Dont serve up a plate full of food. put food in serving bowls with spoons and allow them to serve themselves.
I also find small kids love stuff like being given cheese and a grater to grate over their food. yes, it messy, but hey.
