I hide food from my almost 3 year old all the time, he's always been a fussy eater and I can't remember a time he has willingly eaten a vegetable, recently he realised that chips are made from vegetables, we used to make them ourselves out of sweet potato, potato and pumpkin, he won't eat them anymore, so I've resorted to hiding them while keeping up with the offerings, he gets 'normal' veggies on his plate, which are almost always thrown on the floor and when that fails he has his hidden veggies, I hide spinach in macaroni and about 5 veggies in my usual pasta sauce, it means we all eat healthier as well and, personally, I find the meals taste nicer. My daughter is completely different, she's always been happy to eat whatever I give her and one of her favorite foods is peas, eventually my son will outgrow his hatred of veggies but I think I'll still mix pureed veggies in with our meals because it just tastes better!
