Childcare in and around Zurich is excruciatingly expensive - around 150chf per full day care and upwards.
If you are not a 'working mum' and only need partial care, then there are shorter care options that are also cheaper because they have lower regulations. There is a sticky in the family section of the english forum that describes the options.
If your child is going to the local primary school, then it's quite likely they have a schedule where the children go home for lunch for 1-2 hours in the middle of the day.
If you are looking for english-speaking childcare for your little one, then I can suggest you look at
www.happynest.ch and
www.childrenfirst.ch but I think they probably don't offer places for a 1 year old, but more like age 3. They might be able to tell you who else is around that takes 0-3 places.
I am familiar with Montessori around Zurich and happy to take messages via PM. My work is with 0-3 in long-day-care, and we have places, but it's for care from 7am to 6pm not just mornings, although I am looking at whether we can offer a toddler class that would be 8:30 - 11:30 for either 4 or 5 mornings per week, in Adliswil.
There are other options around. The prices, hours and regulations certainly vary...
