I will be a FTM and am feeling totally clueless about what to buy for our baby due early July. What sort of bedding do I need for a summer baby? From what I've read baby sleeping bags are the best option but which tog level will I need for summer and how many will we need at a time? We don't have a dryer so it they need washing we'll be relying on sunny weather. Is there any difference in terms of safe sleeping between the cheaper ones from supermarkets and the more expensive brands? I expect our room to be pretty hot in Jul and Aug which is a bit of a worry but will of course try to bring the temperature down by oppening windows in the evening.
