Ok, did the ebay ones come with an insert?
Microfiber cloths wont be very absorbant so you wont get very long out of them, if you already have microfibre inserts then i would buy some help inserts (easy peasy hemp ones are fab and very cheap) and put the hemp under the microfiber A better combo would be to ditch the MF alltogether and go with bamboo and hemp (hemp under the bamboo) but obv that comes with cost!
Your not useless, cloth nappy is a learning curve...you will get there
ETA how often are you changing? we change cloth nappies every 2-3 hours with prefolds and every 3 hours with a fitted nappy...we dont use pocket nappies as we got alot of leaks...
ETA in your classifieds listing you have fleece inserts for sale...no inserts would be fleece as its not absorbant at all...its just a stay dry fleece LINER that goes between your babys bottom and then inner of the nappy...if your using these inside the nappies you will absolutly get leaks and it wont absorb the wee...they are not inserts. Inserts would be either cotton, microfiber, bamboo or hemp.
