I can't really work on more than one thing at a time.
Ironically, now that my children are older and gone quite a bit, I find it harder to work when they're not around. Too much free time!
Mothers always find ways to fit in the work - but then when you're working, you feel that you should be spending time with your children and then when you're with your children, you're thinking about working.
I feel more influenced in my own work by dreams than I do by other writers' works in a way. Or by popular culture, movies - what else is there to write about than love and loss?
