Trying to keep my very picky eater 3yo healthy as we’re (hopefully) expanding his diet. Right now the only foods I can get him to actually eat are McDonald’s, a specific brand of yogurt, banana bread, some crackers and some bars. Refuses any beverage besides water. (He’s likely on the spectrum.)
I’m not trying to downplay the reality of serious health concerns sometimes being behind food habits, but I think I need to say…
Picky eating is an absolutely normal part of child development. Anecdotally, both of my kids went through two distinct phases of picky eating, at around 3-5 and 8-11.
They gradually grow out of it. All you can do is try to make sure what they are eating is nutritious enough while they are going through it.
