I love my children, but boy, do they keep me up at night. I reckon over the last three years, 98% of my nights have involved being woken up multiple times, often for stretches of 30 minutes plus. The other 2% of the time I am away at conferences. Things were just settling down with our last one (by settle down, I mean just up once a night) when we had the next one. I think my partner has it even worse at the moment with our four month old!
Lack of sleep can affect us in many ways, but did you know in some ways it is the equivalent of being drunk?
