God, I know exactly what you mean about walking like a pensioner, it's horrible isn't it??? dp says I waddle too, worse luck.
Things to look forward to:
Sleeping on your front, back, side, upside down if you want!
Taking whatever over the counter meds you want (oooh zovirax, I've missed you!)
Wine! Vodka! Wine!
Getting back into clothes that haven't fitted since march
Thundering down the stairs without having visions of tripping and landing bump first on the deck
Running about picking stuff up, scrambling under the bed, stretching on tiptoes for the last can of beans, not asking other people to do EVERYTHING (so it never gets done) standing on a teetery chair whenever I want, wearing tight impractical pants, catching spiders and slugs and taking them out instead of just swearing wearily at them because I know I can't reach up that far/down that low.
....and last but not least... BABY!!
