I knew a mother who had a rather unique approach. She fed her kids the usual baby food and strained meats, but she would eat vegetables and salads in front of them.
For 2 years she told them, “No you can’t have any of my food—it’s only for adults/big people.”
Finally, she gave in and let them eat salads and veggies. They couldn’t get enough of them, since they were now big people. The ‘green’ habit lasted.
LOL...that’s a great story.
