We just got back from a 5 day trip and hoo boy, that was a potty training fail. LO peed all over my friend's beautiful house! She even pooped in underwear once which she has never done. The last day she was in a pull-up all day (we were on the plane or in the car most of the day).
I was sure we were totally screwed but today she's been completely back to normal! She has told us every time she needs to go and holds it until we get to the bathroom. So it has to be just because she was away from home and out of her element. We have not had any issues with going places like the store, playgrounds, friends' houses, etc. but I guess the travel really threw her off.
I'm sure it's totally normal and I'm happy that she seems to have reset without any effort on our part - but I'm wondering if this will be the case every time we travel? We are going out of town again in just a week for Thanksgiving.
