Hi and welcome to COL! You have so much to look forward to - I have just been out for a nice active walk with my 5 month old and far from being tired he's tearing round and round the living room snatching up everything he can find!
We've had the greatest fun ever since we got Clive.
We don't have a crate but we do have a puppy pen and it's been invaluable. He loves it and sees it as his safe zone, and it gives us peace of mind! Also, I second the advice on getting Gwen Bailey's book, we've used it loads.
Look forward to seeing pics once she's arrived.
