I never used a grobag or sleeping bag for my other two but for some reason I've just bought one for my 7 wk old. It is 2.5 tog and I know you aren't meant to use any other blankets with it, but does it really keep them warm? Mine says that he should be in it with just a vest and pj top. Apart from the fact that pj tops don't exist for small babies (they are all sleepsuits at this age), I'm sure he will freeze. Doesn't seem to have any padding on his top half either. Will someone tell me how these are meant to work, and whether you pay attention to their dressing recommendations or just bung them in in warm pyjamas??
Bit confused.
