With an otherwise varied diet is this something to be bothered about? 3 and a half year old eats no greens whatsoever. I'm not counting cucumber as he only eats those cut into half circles and leaves the skins.
He eats all sorts of things like eggs, curry, tuna, spaghetti bolognese, sausages, cheese, chicken, humous, yoghurts, porridge, nut butters, cucumber, corn, carrots, all sorts of fruit. He has a multivitamin every day and likes to drink kefir some days too.
I think his diet is good for his age but just won't touch greens of any kind. Just keep putting them on his plate and don't bother about it? Start blending spinach into bolognese? 🤷🏻♀️
