Its so frustrating isnt it hun
Unfortunately though , as i dont think you'll want to hear this , it wont get better until she p/t now as this is all about bladder control and not really just about being a heavy wetter iygwim?
When you say she is 'out -peeing' whatever you are using , what time scale are you talking about hun?
H could NEVER go more than 2 hours per nappy in his last year (so from 2 yrs to 3yrs) so i never expected more than that...when he was very young we used to get 3 hours maximum sometimes from a nappy but it was very rare , so tbh we've always stuck to 2 hours.
Nappies we were using for the last year were -
BBSS large , with the combi insert , and a bamboo booster , this owuld last 2 hours unless he had a massive pee lol! Couldnt use any other pockets at this point as they all wicked very quickly - infact i often DID have to use pockets if id run out of fitteds but under wool as it didnt matter if they leaked then!
WNNL large , with both parts of the lay in booster doubled over to the front plus a hemp booster , so his wetzone would have about 14 layers , this again would do 2 hours , occasionally 2.5 hours...
HL bedbugs M/L , with the 2 lay in boosters it came with and a hemp insert
FF large , with the 9 layer insert plus a bamboo insert
Sorry , i dont think ive been any help at all there hun just wanted you to know you are not alone in the 2 hour changing , and that the only solution may well be to just change often rather than trying to change your whole stash this late on
