我小时候想要什么就有什么，英文怎么说？

以上回答都不错，但都有些直译。“就有什么”要表达的意思实际上是“就能得到什么”，因此，get要比have好一些。我觉得应该这样翻译：

I could get whatever I wanted when I was a child.

I had what I want when I was a child

I would have everything I wanted when I was young

I could have whatever I wanted when I was young.

我小时候想要什么就有什么

What I want when one was young what to have right away
