cloth diaper for preemie

Freak

i am trying cloth diapers for my 4lb 9 ounces, so far got

osocozy prefolds in preemie with

thirsties diaper hook and loop in preemie and

rumparooz in newborn.

but it is leaking 😟

pee leaks out through openings near thighs, not able to seal it even with snappies. her legs are very thin.

any suggestions from mommies with preemies? how did you make it work? or should i wait till she is already 6 pounds to begin with?
