I would not let the girls get their 'L's' until they had done the local driver course and get their 'L's' during that time.

I couldn't cope with teaching them said the was DH's job which he did and well. They both had a great instructor for the last few months and wouldn't take them to get their 'P's' until he was sure they could drive for life not to get their license.

A good instructor is worth his weight in gold. Make sure he allows you to go with them during a lesson, amazing how their driving changes with a parent in the back seat
