We had the same thing as DD had only just turned 2 and was starting to communicate when she had done a wee. There was no chance of her picking it all up because we moved house and because of this, she was unsettled for a little while (plus mummy was pg ) We then had a few big and small disruptions through out the rest of the year so she never really caught on despite our attempts. However, everything has been calmish now since Christmas and 3 weeks ago I introduced the training pants (she is now just past 3yrs) and it only took days! Now she is a day time potty user pro!

I guess you could keep the subject of the toilet in play and the occasional experience on the toilet. It may not hurt to buy a potty and just have it sitting around maybe (?) but because you are moving, it is good to keep as much in their little lives as stable as possible, sometimes tt can be a bit daunting (for everyone )

Just my thoughts but hth
