HI
We are an English/German family in the local area
It is true to say that there are not many opportunities for German speaking children in the area (covering Chelsea/Battersea/ Clapham/ Wandsworth etc) So much so that it is actually my intention to set up a German baby and toddler group. I am in the early stages of gathering names and emails together so hopefully in the next couple of months we can start something.
Heidi and Peter is certainly worth a shot.

Also try the German YMCA- they do a toddler group on Wednesday afternoons

Musik Garten is also a lovely thing to do

Also the Bolingbroke Early years centre is a good meet up place. I know a few local lovely German mums and babies/toddlers meet on the Friday afternoons there. Its not officially a German groupie but you can make friends with other German children etc.
I hope this helps.

If anyone else reading this is interested in doing a local German babies and children group please Personal Message me with your name and email and i will be in touch directly when we start the new group.
Thanks
