It is so hard and frustrating,maybe she is not quite there yet!? Would she respond to a sticker chart,I never used one but people do have success with charts. Alex is nowhere near ready yet sadly as I would love to be totally done with nappies.
I know though they will only do it when 100% ready,ignore that girls are easier though phrase everyone says as it is rubbish lol!!
I hope she is just having an off day x
