When you’re trying to get a kid out of diapers as early as possible- to avoid the thousands of diapers, and trees, needed per year-, there are a few locations that can prove challenging for getting a tiny tush on a toilet.

In this video, we travel by train with our faircompanies baby- now nearly two years old and mostly potty-trained- to visit her grandparents. When riding the rails, we’ve found that BYOP (bring your own potty) works best.

We also have a videos of Inés starting the process at 16 months, doing quality time on the loo, tips from grandpa on pulling down her pants, on learning to use underwear and training via Skype.
