Sizing help - nappy nation AIO

[tiggercats]

I have a preloved size 2 nappy nation aio, but I've googled and can't seem to find any sizing info for them. Does anyone know what weight a size 2 fits?

As far as I can tell it is an older one, it looks like this

Copied from a site i found hun

Available in size 2, this nappy can either be used as a second size nappy to fit from 6 months to potty (18-20lb up to around 40lb). With five layers of bamboo between the legs, this nappy is absorbent but trim.

This nappy may also be used as a One Size nappy, by folding the front over outwards and overlapping the tabs on top to reduce the height of the nappy. Secured with a Nappi Nippa for best containment, the end result is economical and slim for a one size nappy.

This is for a different nappy nation nappy but im guessing the sizing is the same
