You can chuck them in the boot of the car in place of a pram for the first few weeks (and even months!) of baby's life. Especially handy when your pram weighs a tonne like mine did and you have had a C-section like I did... It meant that when we were out I could just carry my baby and when we got somewhere I could put him down to sleep - even if there wasn't alot of room like in some friend's houses.
When it came to bedtime, I just put the basket beside my bed and was able to respond to any of my baby's needs in my sleep-deprived state without having to worry about negotiating the piles of washing, books and other baby-related paraphernalia that littered my post-baby-bedroom!
The Moses Basket that we have been able to get here at Beetle Bugz are exactlly what we used with our son for the first 3 and a half months of his life. He bunked in our room until we disturbed his sleep a bit too much with our snoring! So off to his own cot in the basket he went until he was ready to be put into his cot. This Moses Basket is so long too that baby can stay in it for much longer than any of the others on the market at the moment (Very important to us as we have a HUGE baby!).
