Babysitter needed for 1 or 2 children in Dietikon

Our younger girl is 1 year old and goes to Kita. On the week days we might need help when she is sick or has a holiday in the Kita. Our elder girl is 6 years old. On the week days we might need help when she has holidays or days off in the Kindergarten, or recovering from the sickness. On the weekend, we might need help with both for 2-4 hours just to get some time for yourselves. German, English and Russian languages preferred.
