Thanks Suzanne and jo jo for your message of encouragement. Will try library for Dr Ferbers book so will have all the facts before I start.DH is away on course for a month at moment so have no back up so to speak. plus i am away for 10days next week to inlaws and am fortunate enough to call them inlaws instead of outlaws!?! So I will be well rested after trip up north and feel able to go for it and try CC and hope my wee pet will get through it and everyone will be happy and well rested again. So will keep you posted when I actually start proper to do the cc and hopefully it will work for me.
