Yes — babies and toddlers travel on the Caledonian Sleeper, and children aged four and under go free (one free child per paying adult), so the fare side is easy. The practical side needs planning, because cabins are compact and the berths are bunks. Travel cots are not a standard fixture of the rooms, so if you need one, contact the operator's team before you travel to confirm what's possible for your room type rather than assuming — some families bring a small travel cot or settle a baby on the lower berth, but check the current safety guidance first. For sleeping, the lower berth is the sensible place for a small child; never leave a baby unattended on an upper bunk. Night feeds and changes are workable but tight: rooms have a washbasin (en-suite in Club and Caledonian Double grades) and limited flat space, so pack a compact changing mat and keep essentials within reach. Interconnecting Classic rooms give a family two adjoining spaces, which helps with an early bedtime and night wakings. Book early, as interconnecting rooms and the cheapest berths go first. Confirm children's terms and any baby provision with the operator when you book, and flag your needs so the crew can help make the night easier.
