Being able to wee and poo on the potty is a complex process that can’t be rushed – your child needs to be able to recognise when a wee or poo is coming, to hold on long enough to get to the toilet, to remember where the potty is, and to pull down her pants in time to wee without making a puddle. She will also need to be able to understand simple instructions or she won’t know what is expected of her or how to tell you she wants to go to the toilet.
