i find greenkids to be quite wide in the crotch, i got mine second hand so not sure if they are the same as the ones they sell now.
if you are concerned about nappies being big on your 2 year old, osfm nappies are definitely gonna be too big on a newborn/young bub. i prefer sized nappies for this exact reason.
how big is your dd now? itti bitti have a few clearance nappies on sale including a pink medium itti bitti snap in one for $18. fits 6.5kg - 12kg
the cloth nappy hunt is also on at the moment with many of the nappy companies having sales, and you get a discount if you register with the cloth napy hunt.
