Years ago I worked part time because of childcare....I worked nights and the hubby days so there was always someone at home....sometimes in the holidays I managed about 3 hours sleep before I went back for another 12.5 hour shift. When my son was older I worked fulltime and did a degree in my own time, travelled 140 mile round trip once a week to take my elderly mother shopping, ran a home etc etc etc.....Claire doesn't know the meaning of tired....I've been so tired I've cried....and I'm sure there's plenty of us working mothers who can relate....thank goodness I did work hard as it meant I could retire before I was 55!!!
