We have fallen into a bit of a pattern with 13-week old baby in terms of nap times and bedtime. This weekend I need to take him with me out for the day on the train to visit an elderly relative, so at his usual bedtime we will probably either still be on the train or be driving back from the station. I think he'll fall asleep either in the car or in the sling on the train when he's tired, as he usually sleeps well out and about. But when I get back should I do his bedtime routine later than normal (bath etc) or do I just miss it out and treat it like a night feed when he wakes up? What does everyone else do?
