Where is the Mummy Off Switch?

It's 3am in the morning and I've just fed my baby. I make my regular trip to the loo and as I wash my hands make a mental note "need to buy more hand soap". On my way back up the hall I check on my son, pull up his covers and do my usual check of his forehead just in case there is a temperature sneaking up on him. Even as I get back into bed I pull the covers over hubby to make sure he doesn't get cold.

So my question is, where is the Mummy off switch?

Women are always multi taskers but after you have kids you just seem to be "on" 24 hours a day 7 days a week. Always writing those mental lists of what's next, what goes in the school bag tomorrow, what's for dinner, where did I put that??

Where always told to make time for ourselves, soak in a bath, read a book, get our hair done. I do these things, but even then I struggle to stop my Mummy brain working me over. I'm going to be especially brave here and say that even when I'm in the midst of "special time" with Daddy I've had a thought about washing or a job I have to do. Of course only in the early stages and it is most definitely not a reflection on Daddy, it's just this darn Mummy brain of mine.

I think it's almost the opposite of how men can just block everything else out and focus on just one thing, whether it be the job at hand, the footy or a pair of boobs!

I spoke to hubby about this and he says it all ties back to the Cave Man Days. Men just had to go out and hunt but women had to tend to the kids, the animals, the cave and pick the berries. We also decided that men tend to have a natural provide and protect instinct for their family. While us Mum's have the organise, nurture, protect, provide, feed, clothe, bathe, entertain and anything else under the sun "instinct"!

So it is an environmental thing or a biological thing. Do stay at home Dad's get Daddy brain? But again my question is, is there an off switch?
