Martha was struggling to sleep, losing her hair, having palpitations, suffering tinnitus and was eventually hospitalised for deep vein thrombosis.
She would come home from her job, as her daughter Amelie said, "grumpy and stressed".
Martha described "getting home, eating, and working again. I wasn't the best mum that I could be. It was a bit of a blur after work. It was constant."
Something had to give - so Martha changed her 60-hour weeks as a teacher for 30 hours a week working from home as a virtual assistant.
Amelie and her brothers, Otis and Barnaby, suddenly had their mum around again.
And research has backed up the family's experience, with neuroscientists agreeing it's good for children for parents to be more available.
