Is the diet a a restriction or, a stroke of luck for a child growing up in this generation?
For sure the latter. Despite her food allergies, your daughter can be super happy with parents which teach her to have a healthy, good relationship with food. It's something that's almost too banal to really reflect upon, but it's something i'm SUPER grateful to my parents for. They always took the time to cook me a nice, diversified, healthy meal each evening. I wasn't allowed to drink softdrinks until I was 16 years old, I learned not to exaggerate with candy etc. These are little rules easily learned, but they have such a big impact in living a healthy lifestyle without having to think about it too much or really put in the effort. i'm healthy because I've never known otherwise. It's been like that for the past 24 years, it's a habit. And i'm super thankful for that.
There are so many little things that the parents/family can affect that become long-term habits.
