Need a bit of advice, my 22 month old will go on the potty at home no problem and has done for about a month or so. That's for wee and poos. She will walk around without anything on the bottom half. Trouble is as soon as she has knickers or trousers on without a nappy she just goes in her trousers. I know she's still very young so I won't push her Any suggestions X
She is very young. It is great that she can use the potty sometimes, but don't assume that means that she really understands, or that she is neurologically capable of using it reliably all the time.
I would let her run around without the bottom half when possible, but put nappies on when going out. You can offer her the opportunity to use the toilet when you go, if it is clean and accessible, but be very laid back about it and don't comment if she doesn't want to.
