All during our journey Peter has been on road potty training too. He is almost fully potty trained at home but on the road it has been a challenge. He did better than I expected. He told us each time and we would pull over to a rest stop and go into the bathroom. Afterwards I would sing his potty song that I made up. He would sing and dance to it.
Anyway our travels with Peter in the car were great and I am hoping our next adventure will be just as good. Hopefully our next trip will be on a plane. Fingers crossed that that trip will be just as good.
