Any time management tips for working mums?

As a working mum, good time management skills is essential for the mummy to juggle both the family & her work well. I cook everyday for my child so I will prepare the ingredients after my child has gone to bed. So everyday after work I just need to cook the ready prepared ingredients & dinner is ready after our shower. Flexible working arrangement allow by my pro-family company also help greatly in my time management. I'm allow to work from home if I cannot complete my work in the office so I can be punctual to pick up my child at the end of the day.
