Can you remove creative mode in Minecraft?

My daughter loves Minecraft, but she only ever plays in creative mode. I d like her to play more in survival mode so that she can gain a bit more out of her gaming time. Problem solving, planning, etc. She is so timid that she doesn't want to do anything even slightly difficult, so I'm trying to force the issue. Looking for single player solutions.

It is a feature in the game that can't be removed however you can make it harder by disabling cheats so she can't use commands to enter creative mode.

You could set your daughter into a survival world and disable cheats so it is impossible for her to enter creative. But if she creates the worlds on her own then she could exit the survival world and go into a creative one.
