Some great ones that I used for RIley, who was also in the teeny tiny gang. Ittti's, If you can get some pocket bots (I think they stopped trading) but were super small pockets. I have one left over and I swear it wouldn't even fit on Lola's foot!
x-small sandies - they lasted a long long time
Is it lollipops that are long? or another brand like that that starts with a B - but not bamboozles
I had massive sucess with x-small bambino mio covers, they run really small
diddy diapers - loved those
That;s all I can think of for now
