Working mothers, please help me out!!

I am completely overwhelmed by everything at home. Since I returned to work and the nanny is here three days, it is just out of control.

I struggle to keep the house in any way tidy. I know it's useless while the kids are awake but even when they go to sleep, I just can't seem to keep it clean.

I haven't vacuumed in, I don't even know how long. The bathrooms - two weeks maybe? Who knows. Basically all I manage to do is clean up after dinner, put some washing on or out or away, try and tidy and collapse.

I'm only working three days. I look around and feel sick at how disgraceful it is here... But it is all I can do to keep my head above water here.

How on earth do I get on top of things?
