I'll probably just use the Moses basket for DD2, migrating it downstairs in the morning and back upstairs in the evening. But then the majority of time it'll just be me and DD2 at home during weekdays - or DH will be around to do the carrying-! We will have the cot set up already in the nursery if ever needed.
All our family live too far away to visit as a day trip, so we'll always have some manner of travel cot or similar that's either kept there and set up already, or that we've taken along with us.
On the rare occasions I go and visit a friend and intend to stay through a nap time, I'd either have the Baby Safe Sleeper with me and let DD2 sleep in that, or take the Baby Bjorn Bouncer along. Not ideal for constant use, but the occasional time it'll be fine.
I reckon that encouraging baby to sleep with a bit of noise in the background is a good thing, gets them used to it early on. :) Means now that DD1 will sleep through almost anything! But that might just be luck.
One thing I'm currently arranging is to get another hand rail put up our stair cases. Mostly because I tend to carry babies in my left arm, which currently means I can't hold onto anything when coming down the stairs as the banister is on the other side.
I already had a nasty fall down the stairs before I was pregnant - don't want a repeat performance with a tiny baby in my arms!
