What are you doing with your toddler on a rainy day in London?

[FeelingLucky]

Need inspiration.
Was thinking of Museum of Childhood or any museum/gallery but wondering if there's anything more exciting to do on a rainy day in London.

We're in North London

We're in south london so heading to south bank to day and tate modern tomorrow - might see you there !

oh, south bank's an idea - anything interesting on there today?

London transport museum is really good if your little one is into buses, trains, thomas the tank [ ususally boys]
My one has loved it since a toddler
very interactive and loads of space to run around
Bring a book
