Jlt,
Thats fantastic! Bedtime story telling is definately an art which takes practice. Your son's repsonse's to you is definately an indication you are doing it well!
I too have also adopted PR skills when reading to my children ... yep, I Photoflip and rapid read and this usually take me no more than 45 seconds and story telling is done! After learning PR - who would ever think that bedtime story telling would be an arduous task!
