So we're off to London this weekend for a few nights - we have a flat down there that we rent out and the tenants are changing so we need to do some works on it. We are taking our 3yr old and 20month old (he has Downs so can't walk yet). What daytime activities are good for those ages? Bearing in mind they still need a 2hr daytime nap which I always think scuppers things somewhat! I lived in London for over a decade but my mind has gone blank with regards to what to do with kids! Have already ruled out Aquarium and Zoo as we have those sorts of places near where we live. Thanks in advance for suggestions!
