Nancy,

I have a mild case of spastic CP, but I could never shave myself with a
regular razor.  I could never get everything without seriously injuring
myself!  So, I've found an electric razor to be a great thing.  Also,
when I first had to start shaving, I used Nair.  I lathered myself up
with it then rinsed off when I took a shower/bath.  That worked well and
kept hair from growing back so quick.  So, if you do end up having to do
this for your daughters, I would suggest these two methods.
