Thanks everyone so far for your responses to my garbled post.
I'm really looking for help with the younger one, as the products we still need for a 2 year old don't seem as mysterious. I was told that the nappies I'd been given are bigger than newborn size, as many of the replies that the giver had received on Freecycle were from people who hadn't had their babies yet.
Most of the nappies are from Green Baby, and there are about 6 wraps, several of which are from Motherease. I've put them back upstairs and am breasfeeding baby at the computer and hoping he'll go to sleep so can't go to check.
