I've not done it yet, but in preparation we've been watching birth videos and talking about noises I might make (!). I've got a bag of sticker books, crayons, fuzzy felts and a couple of new books that we'll get out if she's awake and I'm planning to go and buy a new toy today that should have a bit of novelty value to keep her entertaining herself for a while!
I've also enlisted the help of a few friends who have said they could take her to the park if necessary, and MIL will come and stay with her should I need to transfer.
It's all a bit of an unknown really! Very hard to plan for something when you don't know when it will be or how everyone involved will feel.
