Hi Suzie,
Good luck with the birth of your baby, I hope it all goes well.
Activity for newborns can simply be just changing their diaper, and talking to them.
Start the EASY thing straight away from day 1 if you can. I wish I had.
If you can get your baby into his crib from Day 1 I recommend it as I have seen so many people having problems getting their babies in cribs, because they have become so used to sleeping around their parents, or in swings/bouncers and so on. Start as you mean to go on and stick with it.
My baby slept downstairs all the time, with us, because I had a C section, and couldnt keep going up and down the stairs, so when it came time to put him in his crib in his own room we had a bit of a battle. He sleeps in his own room fine now, but I wish I had put him up there from the beginning to save him the distress of suddenly being moved bless him.
