Former Green MP Holly Walker on life in Parliament as a mother, and a woman

Each morning it felt like I was tearing myself in half leaving her, even though my partner brought her in for a feed at lunchtime.

I left caucus and select committee meetings at regular intervals to express milk, and found myself with an out-of-control oversupply problem (don't ask). She was not a "good sleeper".

My nights were spent in a kind of half-life, wedged in the crack between my bed and her cot. I was chronically sleep-deprived and increasingly anxious. I checked myself against an online post-natal depression scale and got a score that I didn't want to think about.
