I want to get rid of the emergency call button on an iphone?

My granddaughter (age 2) has accidentally pushed the emergency call button twice in one week on her dad's phone. We need to remove the button now!

You actually can't remove the button as it is a core part of the operating system.
If you are using an old iphone version (around 5 or 6 i believe) you can jailbreak the iphone and remove it.
However, you could just unlock the phone each time for your granddaughter before she uses it so there's no chance of hitting it.
Unfortunately, these are your only choices.
