DD is 2.8 and has been properly PTing for about 2 months. She's doing great!
DH is taking her to his Mum's for the weekend which will involve 45 mins on the train and 45 mins on a bus (normal bus, not coach with a WC) so she'll probably stay in buggy in the pram space.
He wants to put her back in nappies for the journey. I'm not so keen, but I'm not the one doing it.
Advice please.
