New drama/play baby class advice

[user1494854861]

Hello Everyone,
I am an actor hoping/trying to start music and drama classes for little ones, aimed at working towards there confidence and social silks but mostly for some fun for mummy's and babies - each class would run for an hour and would be probably 3 slots ages 0-1, 1-2 and 2-3.
I know there are quite a few out there and really wanted to some help as to where there maybe isn't any of these sorts of classes at the moment and would mummys like to have a group near them?
I'm thinking Balham/Clapham/ Streatham though there are quite a few around Clapham already?
Basically any advice from real mummies would be amazing and so much help. Thank you in advance for your advice and help
