Hey Rosey Nearly that time already... the last 6 months have just flown by!!
With DS I honestly didn't do much physically. I did work casually up until the week before I had him so i was on my feet a little bit. But if you take the 'traditional' view of women who do housework (scrub floors & sweep), wash clothes, hang washing etc. Anything but sitting in a recline positioned on the couch it gets bub in a good position to birth. So if you are busy in nesting mode and need to get things 'clean' for bub then that is good. It's not going to hurry bub along any more than normal but it just makes sure that the chances are higher of it being the right way/position. And it keeps your mind busy too
