I try to balance it out on the whole. Being a mum is always the priority. Next, it's taking care of yourself. Right now, I get to only work two days a week - it's a dream. I can't imagine how hard it is for mothers who work 40 hours a week.
I like bringing the girls on set, but if I can't do that then the next day I feel I have to be uber-mum to make up for it. Then I'm exhausted and feel like I'm running in fumes.
