it could be much worse. I work with kids who have chronic illnesses and I'm sure there parents would say that they wouldn't mind them waking up every hour at night if they were healthy and happy.

Thankyou LoriRae...I have been feeling really down and not getting much sleep either, but it really is great to get some perspective isn't it?
One of our friends DD's is only 5 years old and terminally ill, they will probably not have her much longer, and as hard as sleep deprivation is I consider myself the luckiest mother on the planet to have a happy, healthy baby. Jack is waking every couple of hours at the moment and just wants to laugh and play all night, I am so lucky to have him.
