Has anyone bought the kids eat in color picky eating guide?

My kid has been picky eater since 9months old. Early intervention didn't seem bothered cuz she has a list of food she may or not not eat consistently that is long ish (it's mostly fruits yall). So idk when taxes come I was thinking of getting the guide and solve this myself hopefully. But it's 150 bucks. So I'm asking yall. Was it worth the buy?
