A toddler in London is harder than a baby and easier than a five-year-old, for one reason: they can walk but will not do it for long, and they still need a sleep in the middle of the day. Plan one ticketed thing per day, put it within a single bus ride of the hotel, and work out in advance where the pushchair is allowed to go.
We have separate guides for either side of this age. London with a baby covers feeding, nappy changing and the ETA that even a newborn needs, and London with kids takes over from about four upwards. The transport mechanics of a buggy on the network are in getting around with a pushchair. This page is about the awkward middle: roughly eighteen months to three and a half years.
The age thresholds that catch people out
Toddler pricing in London is not one rule but a patchwork, and two of the entries below are refusals rather than discounts.
| Place | The rule for a toddler |
|---|---|
| Tower of London, Windsor Castle, Buckingham Palace, Kensington Palace, Royal Mews | Under-5s free; the child rate starts at 5 |
| Wonderlab at the Science Museum | Paid for everyone from age 3; under-3s free. The day pass starts at £13.50 |
| Thames river boats | Children aged 4 and under travel free, maximum two per fare-paying adult |
| Diana Memorial Playground | Free, but only adults supervising a child up to 12 are admitted at all. Unaccompanied adults may enter only between 9.30am and 10am |
| Coram's Fields | Free, and again an adult cannot enter without a child |
| National Army Museum Play Base | Museum free, Play Base £7.50 per child aged 0 to 8, in booked hourly sessions with strict adult-to-child ratios |
| The London Dungeon | Under-5s are not admitted. The recommended age is 12 and up, and the drop ride has a 1.4m minimum height |
| The Helix slide at the Orbit | Minimum age 8 and minimum height 1.3m, so not an option until well after the toddler years |
Two of those are worth planning a day around. The Diana Memorial Playground reopened in August 2026 after a rebuild, with a new galleon, and is the best free hour in central London for this age group. Its water play is switched off because of the hosepipe ban, which for a two-year-old removes about a third of the point, so check before you cross town in hot weather. Coram's Fields is the Bloomsbury equivalent and useful if you are doing the British Museum.
The London Dungeon entry exists here only as a warning. Families arrive at County Hall with a three-year-old, having booked online, and are turned away at the door.

Where the pushchair actually goes
This is the question that decides whether a morning works, and museums answer it differently. The Natural History Museum charges £5 to check a pushchair into its cloakroom, and will not let large or wheeled suitcases into the building at all. The Churchill War Rooms have no cloakroom and do not permit suitcases. Historic sites are the hardest: cobbles, spiral staircases and narrow doorways mean you park the buggy and carry the child.
The practical answer is to travel with both a buggy and a soft carrier, and to decide at the door which one you are using. A carrier also solves the one problem a buggy cannot: a toddler who wants to be up where the interesting things are.
Three Tube lines have no buggy space at all. Most Tube trains have a multipurpose area suitable for a pushchair, but the Central, Bakerloo and Waterloo & City lines do not. On those you stand in the aisle with a folded or angled buggy, which is why we send families to buses for short hops.
On a bus, the wheelchair space is where a buggy goes, and by law a wheelchair user has priority over it. If one boards, you share the space, fold, or move. You will not be ordered off, but if you choose to get off, the Hopper fare lets you board the next bus within the hour at no extra cost. That is a rule worth knowing before it happens with a sleeping child in the buggy.
Building the day around the nap
There are only two workable strategies, and mixing them is what goes wrong.
The buggy nap. Keep moving through the middle of the day and let the child sleep in the pushchair. This wants somewhere quiet, level and covered: a big museum's least popular wing, a park path, or the top deck of a bus on a long route. It also wants you to accept that you will be standing up for an hour looking at something you cannot really concentrate on.
The hotel nap. Go back at midday, put the child down properly, and come out again at three. This costs you an hour of travel each way and is why we keep saying to stay near your main attraction rather than in the cheapest area. It produces a much better afternoon.
Whichever you choose, plan the ticketed thing for the morning. Every paid attraction in London is at its worst between about 11am and 3pm, which happens to be exactly when a toddler is at their worst too.
Attractions that survive a two-year-old
The test is not whether children are welcome. It is whether the place can absorb noise, whether it is dark or contained enough to hold attention, and whether you can leave in ninety seconds if you have to.
- City farms. Free, outdoors, animals at eye height, and nobody minds a tantrum. The best of them are on our page about city farms and playgrounds.
- SEA LIFE London Aquarium. Dark, warm, level, and takes about an hour and a half, which is close to the outer limit of toddler attention. Expensive at £28 online, and worth it mainly in bad weather.
- The cable car. Step-free, ten minutes each way, a cabin to yourselves, and £7 for an adult one way with children at £3.50. For a toddler who likes going up, it beats every paid viewing platform in London.
- The front of a DLR train. No driver, so the front window is a seat. It is free if the child is under 11 and travelling with you, and it entertains this age group better than most things with a ticket price.
- The Natural History Museum. Free, and the whale in Hintze Hall does the work. Queues form at weekends and in school holidays, so book the free ticket and go at opening.
The National Army Museum in Chelsea is the unexpected one. The museum itself is free and quiet, and its Play Base is designed for exactly this age, though it is charged and booked in advance.
What it costs to move a toddler around
Children under 11 travel free on the Tube, DLR, Overground, Elizabeth line, buses and trams when accompanied by a fare-paying adult, up to four children per adult, and no card is needed. That is the single largest saving available to a family in London, and it applies to every toddler.
The exceptions are National Rail services, where the rules vary by operator, and the river, where under-5s are free but only two per adult. Our page on children's fares on London transport sets out which journeys need a Zip card and which do not.
A toddler costs nothing to transport and nothing to admit almost everywhere. Two adults and a two-year-old will normally pay two adult fares and two adult entry tickets. The real cost of this age group is time, not money.
Toilets, changing and the ten-minute rule
Baby changing on the transport network is mapped: TfL publishes a toilet map showing which stations have toilets and which have baby changing, and its toilets are free to use. Non-TfL facilities may charge. Our guide to public toilets in London lists the reliable central options.
In the museums, the useful thing to know is that the quiet rooms double as feeding and changing spaces. The V&A's Quiet Space on Level 2, next to Room 73, is explicitly for infant feeding as well as for visitors needing a break, and the Natural History Museum's Contemplation Room on the ground floor of the North Wing serves a similar purpose.
Then there is the walking. A toddler covers perhaps four hundred metres before negotiating starts, so treat every "it's only ten minutes" as twenty-five. That is also the case for the walk between Tube platforms at the big interchanges, which is why a bus from door to door often beats a faster Tube route.
What we would not attempt
Three things, honestly.
A day trip out of London. Our guide to day trips that work with children puts the practical limit at about an hour each way, and with a toddler even that is two hours of pushchair-on-train plus the return. Save it for a longer stay.
A self-transfer between two London airports on a tight connection. Moving between Heathrow and Gatwick takes about an hour and five minutes by coach and an hour and a half by rail, before bags and border control. Our page on connecting between London airports explains why the margins need to be generous, and with a toddler they need to be more generous still.
Dinner at eight. British kitchens serve early, high chairs run out, and a tired toddler in a restaurant at 8pm is nobody's good evening. Eat at six. Eating out with children in London covers which chains genuinely cater for it.
Frequently asked questions
Do toddlers pay to travel on the London Underground?
No. Children under 11 travel free on the Tube, DLR, Overground, Elizabeth line, buses and trams when they are with a fare-paying adult, up to four children per adult, and no photocard is required. National Rail services within London have different rules, so check the specific journey.
Can I take a pushchair on the London Underground?
Yes, and you do not have to fold it, but most stations have stairs or escalators rather than lifts. The Central, Bakerloo and Waterloo & City lines have no multipurpose buggy area on the trains at all. For short journeys with a toddler, buses are usually less work than the Tube.
Which London attractions are free for under-5s?
Most of the big paid ones: the Tower of London, Windsor Castle, Buckingham Palace, Kensington Palace and the Royal Mews all admit under-5s free. Wonderlab at the Science Museum charges from age 3. The London Dungeon does not admit under-5s at any price.
Where can a toddler nap in central London?
In the pushchair, which means somewhere level, quiet and covered. A large free museum's less popular wing works, as does a long bus route from the top deck. If you can, going back to the hotel for a proper nap produces a far better afternoon, which is an argument for paying more to stay centrally.
Is London Zoo or the aquarium better for a two-year-old?
The aquarium, in bad weather or if you have only an hour and a half: it is dark, level and contained. The zoo is better value and more interesting but assumes a child who will walk for three hours, which is exactly what a two-year-old will not do.
