As much as I’ve ridden Amtrak I never paid attention until we had a baby. We’re doing a 6 day 5 night trip GBB to LAX then on the SSL/TE the longer way home over the holidays. When she was 5 months and in her car seat the dining car wasn’t an issue, her and her car seat fit in the booth. Now that she’s 10 months and using a high chair I don’t know what to expect on the train. Obviously no high chairs on the train. Is there even small booster seats available? I have a feeling we’ll have to do last call to get a table to ourselves and just hold her at least for dinners. Possible eat in room a few times.
