Hi @Scott Baxendale 
such a sweet voice , you should encourage to sing more & try to listen to her songs to see if she thinks they are good
you must be very proud
My wife sings to our baby granddaughter & she is tone deaf so the baby is also learning to sing out of key
i hope she can develop & start to sing & play a instrument 
success & looking forward to hearing more songs  from her & you must be having a great time doing these songs
