Postal Museum

I’d look at Postal Museum and the Mail Rail ride. Sure it’s for kids but I really loved it more than my niece

Postal Museum (this is one of the best museums in London and no one ever talks about it)

Postal Museum, London Transport Museum, Forbidden Planet, Design Museum, The Viktor Wynd Museum Of Curiosities, Prince Charles Cinema, do an escape room (eg clueQuest), visit a boardgame pub (eg Badger Badger Deptford)

Postal Museum. There’s a mail train - younger one loved this.

Sorted! at the Postal Museum near Farringdon, and the Mudlarks gallery at the London Museum Docklands are both fun for toddlers.

postal museum or science museum are very kid friendly.

the postal museum nearby has a real mail train you can ride. It’s pretty cool.

Take the kids to the Transport Museum, Postal Museum, Coram’s Fields, Tower of London, etc

London Transport Museum and the Postal Museum are great, especially with kids.
