I do have a 16 months baby daughter and my wife needs some free mornings per week for studing and take care if itself.
Also for the baby it make sense to have some german speaking social activities.
The baby is really active and social, no worried she will love this experience.
Any advice around Zurich/Wallisellen?
Kindergarten in Switzerland is not the same as in the US, it's more like pre-school and children go there from the age of 5. Chec k if you have a playgroup in the area. It would be called "Spielgruppe" or "Krippe".
Yes, its called Spielgruppe and you can find them often over the community, just call them and ask for it.
The kindergarden is from 5 years old like written before.
Another opportunity is a " Krippe " but its mostly charged in percent from your salairy, as the most Krippe are private it is more expensive.
The other option is a Kindertagesstätte, or Kita for short -- this is regular paid childcare in a group setting (so somewhat like a US "Kindergarten"). However, some of these require the children to be toilet-trained, which your daughter obviously isn't, so make sure you ask for a Kita that takes babies. Ful time care (working hours, five days per week) will set you back at least CHF 2,400 per month with part-time care proportional to this.
Try searching EF and Google for "Spielgruppe", "Krippe" (or "Kinderkrippe") and "Kita" in Zürich/Wallisellen.
Look for a child minder - as they would usually charge SFR25 per hour in Zurich and would come for perhaps 3 hours a couple of monings a week. I work for 6 hrs every Tuesday afternoon looking after a 5 year old boy - that is speaking to him only in English!
Just to be aware, Swiss Kinderkrippe usually charges around 150-200chf per day per child. They are not cheap.
Halfdays are possible too.
They also usually need a minimum subscription, like 2 days per week before they will take you.
If you work for a big company, chances are they have some affiliated Kinderkrippe and may have a discount or an easy enrollment policy.
Perhaps you can look for a Tagesmutter (Daytime mother) who lives near you and she can take care for around 10-18chf per hour (standard rates I heard). Some are with certified skills and contracts.
Swiss krippes do not charge so high! I currently pay chf 120-130 per day for my 2yo daughter at a bilingual private (German and English). I used to pay chf 130 at another more local krippe where they speak Swiss German only but that was because my daughter was below 18 months. Otherwise I would have to only pay 115 chf per day. Alternatively you could try going to a Stadt krippe where they charge according to the monthly income of your family.
I take my 2-yo kid to Spielgruppe Rudi Gordon, it is in this leaflet above, page 8. It is the only one in Wallisellen that takes kids less than 2.5 years old. We started 3-4 months ago. It is every Tuesday and Thursday, 9:00-13:00.
Kinderkrippe here in the area costs 105-130 chf (not 150-200), but you have to ask if they have available places. Spielgruppe costs less (10 chf per hour)
