Motherhood has made me into a fast eater and a slow driver.
We seem to eat in relay these days. "Okay, I'll quickly eat this and then I'll take the baby and you can eat". Or sometimes, once every different coloured moon, both babies are asleep at the same time, and you gobble down your meal like the smallest kid at boarding school knowing that one of them will wake up soon and those chips will not taste so good when your next chance rolls by in 3 hours time.
The driving slow thing is not out of concern for their safety. You're late. It's a known fact that it takes you eight times longer to get out the door with two children under 3 in tow. but no matter how early you start getting ready your 2 year old will hide the car keys/decide to walk to the car at a caterpillar's pace/have some drama with the playdoh and and your 4 month old will crap in his nappy/vomit on you just as you're stepping out the door. So you're driving faster than usual to make up the lost time with the playdoh incident when you glance in the rearview mirror and notice that one/both of them maaaay be dropping off to sleep. Oh bliss! Then you'll be able to leave them to sleep in the car and you can savour a moment eating your meal with no limpets attached. So you slow riiiiight down. You drive around the block. You're driving so slow you may stall at any moment. And you drive just once more around the block, because they really are nearly asleep. And one last time because aaaaany minute now. And then a car whizzez by hooting at you for driving so slow and now they're definitely not asleep. So you head back to your destination and as you pull up they're both asleep. Yessssss.
But because you're late the only parking available is where you can't see them if you leave them asleep in the car. So you have to decide. Do you wake them up or do you sit in the car and wait?
