Sleep is something most parents have a love hate relationship with. We would all love more of it and hate having it disturbed.
When your bundle of joy comes along you accept that your hours laid in a soft, comfy bed under a cosy duvet will be less than before and this is a sacrifice you are willing to make in return for a beautiful baby all of your own.
However most of us see loss of sleep as a short term investment when having a baby; so why does it feel that an eight hour stretch in bed is equivalent to finding the holy grail in mummydomland.
