Oooh, Jols how exciting! Um, I had two x-small (Rikki) and two eenees snibs for when he was little, and that was JUST enough. 5-6 would be better I think. What sort of nappies are you planning on using? Remember that I used flats the entire time (and sposies when out and about in the early months) so I really should have bought more covers.
I wouldn't have thought that you would ever have a huge baby LOL so you might well find that you need the x-small covers, but I wouldn't go crazy getting heaps. Stock up more on the small size. N wore smalls for aaaaages. It's hard to know buying online because with the Motherease they state that the x-small and small are for the same weight range!!!! What's with that? Anyway, they are definitely a different size.
Did you use snibs last time?
