I got my Big Softies at Target. There are heaps to buy online, just search it. My favourite is one I hemmed from an old towel, it is super soft and luscious.

Ladies, hit me with your best fold for a newborn, 2.7kgs and a little skinny minny

The triangle is pretty good - fold into a triangle, and then into a triangle again. But I always loved this one. You can tuck the legs in to make a neat little gusset too.
