I think your friend may be better of with a narrow neck'd guitar. I'd recommend a OM steel string guitar but buy a pack of ball end nylon strings and replace the strings.
Another route to potentially explore could be electric guitar; which for the best part of the time have the easiest necks to play. For the beginner too,
light strings could make a difference too.
For someone with 'very' small hands I'd recommend a 24" scale electric guitar like a Jaguar (Fender or
Squier)
The Taylor GS Mini also has a shorter scale, a steel string guitar but once again it is possible to replace the strings with nylon ball ends.
