What to do in London with Teen and toddler

[HopeNope]

Toddler will generally be happy to tag along, but need to find places to go in London that will interest teen girl.

Any ideas?

With a teen and a toddler I'd go to Tate Modern. Lots of space for toddler to bomb about, gorgeous shop (if galleries fail to impress the teenager) and people watching plus the art which as it's all contemporary is never boring. Plus whichever direction you approach from a walk along the South Bank will have loads to interest both - giant bubbles for the little one, buskers etc for the teenager.

One, thanks!
