Thanks for all the replies. I have no idea if this bub will want to be swaddled or in bags. A friend's 2 week old recently started sleeping in bags.

i just bought 2 x 1 TOG in the 0-6 month range. Probably I should have bought them in a larger size, but I think I have issues imaging we'll actually get that far. The grobags were $55 each. I'll definitely look at other brands too.
