I bought one of these for my son when he was born but have used it more for my daughter. I usually put her into a wondersuit and then the grobag witha blanket over her depending on the temp. When you purchase they include a thermometer advising on best nightclothes to wear with grobag with the temp. My kids have had the best nights sleep when in these bags. Unfortunately I can no longer use it as they are both too big for it. It looks like I will have to invest in another one.
