English speaking Playdates/Meet-ups (Stuttgart)

Hi All, we, that means my husband and my 2 kids (3 years and 9 month) are currently living in Taipei, but wwe will move back to Stuttgart ( Schorndorf) - so we are coming back to the roots. After 6 years living abroad my son can speak quite good English for his age and for sure I will do everything to keep it. Thats why my post here. I want to know if there are any english speaking meetings with kids, playgroups etc. where I hav the chance to meet english speaking kids and mums. Thanks!
