London for Kids for photoshoot locations

[shooteurope]

I am a a fashion shoot producer and need advise on beautiful Kids shops in London - vintage toy shops/beautiful cupcake cafes/dressing up shops/just simply gorgeous cool Kids places for a photoshoot I am working on for a well known Kids clothing label. I am also a Mum of 2 - live in Paris and am happy to trade 'insider info' on things to do in Paris and lovely places to go with kids.
My email is [email protected] if anyone has any great advice?! thanks
