Sleeping Bags

I've seen these around on various sites and they seem like a good idea, my little one is due mid summer but being the UK that could mean 15 degrees or 30 degrees! So I was wondering are sleeping bags okay from newborn, do you need a blanket as well or do you pop bubs in and just lay them down on a sheet in the bassinette, is it a case of either wrap or use a sleeping bag and finally would you recommend a particular brand of sleeping bag or are they all much of a muchness?

Look forward to your opinions and advices

Perrrrrrrsonally I would make sure the sleeping bags are made out of a natural breathable fabric - cotton for summer or something like merino (lightweight for summer and heavy for winter) - synthetic fibres aren't so great as they tend to sweat. (Although in saying that I often wrapped Hannah in a fleece blanket and she was fine!)

I love my Grobags, they are all cotton, and they make them in different tog ratings. They come with a thermometer and clothing guide so it's easy to work out how to dress them. Fay has been in one since about 6 weeks old, she was never wrapped and got really wriggly at that point and is still a blanket kicker. I know Grobags are much cheaper in the UK than here as well. Hsve heard good things about the GoGo bags too

Gremlins were wrapped until about 5 months then into Grobags, I like them for the same reasons as Redbedrock, they are 100% cotton and breathable. We also have some 100% cotton Living Textiles ones in summer weight which they are in at the moment, I got them from the Sleep Store and they are cheaper than the Grobags.

I'm just starting Cooper in his Go Go bag. I bought it because I like the idea of natural fibres and they regulate body temperature both hot and cold.

He still likes being wrapped though, so I've just started introducing it in his daytime sleeps.
