If you’re a Londoner, how would you spend one day in the city with 3 yr old?

[AmberHollow]

I’d love to bring my 3 year old down to London for the day with me for something a bit different to our normal routine. I don’t know the city particularly well but I’m fine with tube travel and getting around generally.

What are your “must do/see” tips with a 3 year old who is a reasonable walker (not planning on bringing a stroller), but can’t go miles and miles?

We would probably be aiming to get into Euston around 10am and would want to be back there and heading home by around 2pm. So less than a full day! I don’t really know quite where to start so any tips gratefully received.

Postal museum and the playspace Sorted! Editing to say Sorted is in the postal museum but you need to book it as well. It's not far from Euston so handy for your time slot!

Science museum I would bring a pram they get tired and you can lob stuff underneath.

Science museum top floor you pay but it is brilliant

Transport museum.

St James park to see the pelicans and have a picnic.

Came here to say this :)

Postal museum. Mail tail train. Sorted play area then have a picnic at coram fields (5 min walk)

Transport museum if they like buses trains. Natural history if they like dinosaurs. The latter is free.

The Horniman!

Wonderlab and a 3D film at the Science Museum, lunch at Pizza Express, then Diana’s playground (all walkable). Or maybe the other way round because my kids spend hours in the Science Museum.

Postal museum and then the fountains and market at Granary Square near Kings Cross.

Or Covent Garden - watch some street theatre and do the Transport Museum, Wahacas for lunch

The Horniman for a 3 year old coming into Euston…?

There's so many places to go - depends what they like really.
But really.....bring a buggy. Even if you need to borrow a basic umbrella style.
Not just because of tired little legs but it gets so crowded in London that you would probably end up having to carry her just to not get separated.

The Horninan's a lovely local museum, but really not worth going right across London for on a short visit.

The Wonderlab at the Science Museum is aimed at age 7-14. There are a couple of really good areas for toddlers though (The Garden and The Pattern Pod).

My kid mainly likes to run around though, so I'd head to the river, wander around the Tate modern, see the bubble man, see what's on at the Southbank centre

NB Replay was good (arty soft play), and the Appearing Rooms are fabulous fountains (but if her gets scared you might have to go in yourself and you'll get soaked 😬)

Princess Diana playground is good but check it's open as it was closed for refurbishment.

Natural history museum, dinasaurs only:) lunch there or at the brasserie on brompton road, over to kensington park if playground open, probably in a cab as little legs get knackered, , if playground closed just walk round, look at the ducks, hopefully there might be some horses, cup of tea and cake, home.

Which bit of london? What does your child like?

I’d go to kings Cross, wander round the little park, have a coffee/ice cream watching the canal, see if the little fountains are active (with a spare towel) and have lunch in coal drops yard.

Agree with this, especially in the summer

Another vote for bring the (foldable) buggy. I get knackered walking round and I do not have particularly little legs.
Coram fields, cable cars, science museum, natural history museum. London is amazing, but most small children couldn't care less.

Honestly, most three year olds who don’t know London are fascinated by little things and don’t even need stuff like museums, or ‘attractions’. DS’s favourite things at that age were ‘driving’ the DLR, watching the skateboarders on the South Bank.and going down the steep escalators at Angel (because I’d shown him video of the guys snowboarding). If you over-schedule, you end up dragging a child who just wants to stop and stare around and getting frustrated. They also get very tired very quickly.

Go to see Buckingham Palace and watch the Horse Guards parade around 11 am, not sure if it's every day. Picnic in Green Park or St James Park. Walk to Westminster to see Big Ben and The Houses of Parliament. My 3 year old niece lives seeing the London landmarks You could also get a boat trip on the Thames, maybe Uber boat, I think are quite cheap if you had time

Thank you all so much for these brilliant ideas! I’ve jotted everything down and will make a plan - probably several and aim to do a few trips over the next few months.

Good point about prams. I’m a bit nervous about navigating the tube with one (so many stations seem to lack lifts?) but worst case we could just use cabs.

Worth looking at buses as generally easier to navigate with a buggy than the tube - citymapper app is good for seeing all the different options
