Thanks girls. That's made me feel allot better knowing that other people have that issue too!

I think I am just feeling frustrated at myself as the problem isn't with him as he has had a few tests and they have all come up trumps but the problem appears to lie with me however we don't know what it is as again everything is coming up perfectly normal.

He's pretty cluey when it comes to when I am Oing as we have been doing this for some time now but maybe it is definately a good idea to let him know what "week" it should be happening and let him gauge or take control as to how much (or how little) he can do.

Thanks again sweeties
