Sleep suits and snow suits

Excuse my ignorance here but, how do you know you're leaving hospital with the right baby? This has been troubling me for around four days now. How do you know your baby hasn't been mixed up with somebody else's after it has popped out? There is no way of telling! All babies look the same for around three months after their birth. How do you know your going home with the right one? It'll be three months till you know for sure! This is concerning me.
Also, what's with the buying of snow suits? Apparently we need to buy the expected Baby Reid snow suits. Snow suits? I wasn't aware we were eskimos? Will we be travelling home from Wishaw General in a sledge pulled by huskies? Me, standing at the back of the sledge cracking the whip, whilst Ka and baby cower from the cold in furry suits at my feet, our huskies racing forward, pulling us, their breath puffing out in swirling clouds before their frozen maws as they pant their way through the white, frozen wastelands of Wishaw and Craigneuk.
Sleep suits too. Sleep suits, sleep suits, we don't have enough sleep suits, and apparently we never will. This baby is going to have more suits than Hugo Boss.
Hats, bibs, boots and scratch mittens. Scratch mittens? Apparently babies have a habit of trying to scratch their face off? First I'd heard. Surely they can't be that fully aware to look in the mirror and hate their god given mug at that age? I thought that all didn't kick off till the teens and forever after? (Certainly didn't with me anyway). Then again maybe that's a good way of knowing it is indeed my child - if it sees itself in the mirror and immediately goes for it's own face screaming horribly.
Nesting. The suit buying is all part of the nesting process apparently. A word for what an expectant mother does in and around the home to prepare. Moving things around. Throwing things out. Making way for piles of sleep suits. Buying baby lotions, talcum powder and cotton wool.
Spending money when it's not yet quite needed to be spent, that's what I call it. I've had to empty two of my bookshelves already and the poor wee tyke is not even here yet. All in the name of sleep suits. Who would have thought such tiny garments could take up so much space?
We need a house and quick. Anything bigger than a one bedroom anyway.
I'm sure some of those eskimos must have more room in those igloos than we've got. They always have loads of kids running about. You never seen eskimos on the Michael Palin programmes shouting about how little room they've got in their igloos because of all the sleep suits. Bet the huskies have even got their own room!
