On the train and I have to pee

[piper]

Amtrak train, not very crowded, ds is with me (he's five). Bathroom is two rows back

Do I take him with me?

[softspot]

Uh...yes. Presumably you will shut the door & he will be out of your sight.

[LynnWriter]

Yes, take him.

[Captain Serious]

Yes. Most of those I've been in are handicapped accessible, so you should both fit without it being an issue. You can't leave a five year old unattended on a train. It's asking for trouble. He could wander off looking for you or much, much worse.
