I agree with the previous posts and highly recommend a grobag/sleeping bag.

Our daughter loves to kick all the sheets and blankets off which is not a problem in summer but now that the weather is colder we couldn't do without a grobag. We live in tassie and I am currently using a 2.5 tog and a bonds wondersuit underneath (I add a singlet on really chilly nights) and no blankets. It just depends on the climate where you live.

If you do go out and about a bit then keep an eye open for the travel versions that have a hole to thread through seatbelt/pram strap between the legs because it may save you waking bub.

I would also suggest you google Bloom & Grow Direct (based in Hong Kong). They currently have some winter grobags on sale at half price. I have only used them once but have no complaints. It is all in american dollars but with the good exchange rate at the moment even when you convert and add freight you can often do well.
