You should be able to download the MIDI from Kididdles and then use a notation program to convert it to sheet music. I believe Noteworthy still has a free reader in which you can do that, or if not a very cheap purchased version. MidiNotate is also a very good and inexpensive program. I use it to auto-transpose and it will also give you chords to start from as well as the sheet music. If you Google up those programs you may find yourself easily enabled to do as you want.

But kids also can learn easily by ear-- why not give that a go, from the MIDI?
