Hi. We're a Franco-American family looking for a native Mandarin speaker to come play with our 3.5 year old twins in Mandarin for 1.5 hours every week (other than school holidays), on Tuesdays, Wednesdays or Fridays from 4.45 PM to 6.15 PM or so. We live right next to the U-Bahn station 'Deutsche Oper' in Charlottenburg. Note: this isn't classical babysitting, as we would be home during these sessions; we are looking for help so we can wind down our work days (+ get the kids exposed to Mandarin in doing so). Please message me if this is of interest.
