I think our city break with a child this age was the most stressful holiday weekend we ever had. I came home tearful with lack of sleep.
He was old enough to be very aware of new surroundings, and wouldn’t sleep in the travel cot provided in the room. Or sleep at all.
Or eat on cue at meal times (I.e you don’t necessarily have the luxury of self catering to their usual routine when staying in hotels). Or eat at all, for new surroundings etc.
Being out and about was ok, we found places for him to have a toddle. But yes, whereas Amsterdam and other cities ‘have babies’, the babies that live there have a relaxed known environment for breakfast, a nap at some stage, a home where the parent/s can chill and go about their lives rather than in a hotel room.
I had taken Dc on all sorts of travels from 2.5 weeks old. Abroad at 9 weeks, long haul to a different culture at 8 months, but 10 -24 months was tough.
It was a difficult age. Maybe I just had difficult Dc!
