Please, advice for cultural activity next Wed and Thu with kids in London

[ChocFudgeCake]

I'd like to take the 8 and 6 year-old DCs to a concert (classical music would be great) or some performance or a hands on activity, anything really!! Also I have a 3 year old DC, i'd like to do something with her on our own... Anyone has worked out a plan? Please share it with me, i should have sorted this out before, I don't want to be indoors with all going mad and watching TV only.
Thanks!

Have a look at the South Bank Centre or a free double bass recital at the Foundlings Museum: here and in fact loads more if you look on that site.

A million things to do with a 3 year old. What do you like doing together?

Thanks a lot :) I'll look now at these sites. I don't really know what to do with the 3 year old I kind of just bring her to things for the other DCs, that's why I'd like to give her more individual attention.

Looked at the Foundlings museum, sounds good!

The Southbank Centre is always a good call. As is the Natural History Museum, I always used to take my girls there when they were little, and there is one exhibt about a flushing loo that had a poo in it which they found HILARIOUS. Ahem. I don't know what I've raised!!

Kids also always love Hamleys? Although that can often be a pricey venture.

What about a trip to the theatre?
