Hit it with a hammer and turn them into big cracks.

Needs a new screen, nothing else will "fix" it.

You will HAVE to get the screen replaced, either by Apple or a local Cell Phone repair shop. Since this is a newer phone, with warranty, you will want to go through APPLE, so that if you have any warranty issues during the first year, you will still be covered if they do the screen replacement. If you have a local repair shop replace the screen, you will be voiding any warranty you have left.

Rule of thumb, do not allow toddlers access to items that you do not want broken. And the parent of said child should be paying at least part of the repair. But in the end, it is your fault for not keeping your phone under your control.
