Just stumbled on this thread from a little while ago and it's something I've been wondering about too. From what everyone else has said I guess we'll start with swaddling and then see how things go. I've heard of the woombie but never seen them - might do some research. Someone mentioned that although grobags are expensive you save money on blankets - does this mean that if you use a grobag / sleeping bag type thing then you don't need a blanket n top as well??
