Study claims that mums get nine hours of sleep every night and what are these lies?

How did they come up with this result?

A recent study concluded that mums get over eight hours sleep every night and the mammies are not having it. In fact, the study seemed to find that absolutely everyone, regardless of gender or how many kids you have are getting well above the recommended amount of bed rest. Colour me suspicious. As a parent that generally gets woken up at least once every night I find it hard to believe that an overwhelming majority of parents are getting almost nine hours of shut-eye. Surprisingly, or not as the case may be, the study was conducted by a mattress company. I'm sure they would never be biased with their results right? If you think that I'm joking you can see the results here for yourself. The company have put in the fine print that their results included any type of sleep taken over a 24 hour period. This included napping and dozing. Personally, I think this is a little bit of a cop-out because broken sleep can be as tiring as no sleep. I never feel fully rested after I've been disturbed during sleep. I think that their finding that most parents are getting the recommended amount of sleep is a big stretch.
