We adopted 2 girls (ages 8 and 10 at the time) almost 5 years ago from an African country. They were incredibly picky eaters and refused to try new foods. I have been customizing our meals to accommodate them but lately have gotten fed up with their rude, entitled attitude towards my meals. They are also negatively influencing 2 younger children, who we recently adopted from the same country, but who are willing to eat everything.
I have uninvited them from dinner and they have to make their own meals and eat them on their own. Our relationship is already strained and adding not eating dinner together is distancing us even further. I don't think that I can train them to eat new foods at this point in their lives. Any suggestions?
