‘I blame his parents for giving in to him.”
That was my first thought too. Reminds me of the commerical on TV where the Mother is running after a little girls of about 4 or 5 begging her to eat one more spoonful of veggies, to me that is sickening. No way would I ever run after my children begging them to eat a vegetable....
Raised three, and while we made a point of trying to cater to their preferences, they WOULD eat lots of fruit and veggies. Sometimes it took some imagination on how to prepare. Home-made pizza is a good way to sneak veggies in under the cheese and sauce.
A lot of it is making sure they get a variety of food when they are toddlers, before preferences have a chance to get set.
