My daughter had a nursery for under three s together with another friend. She is a midwife and her friend a children's nurse( hospital trained) They met training as 'Tages Mutter' this is an 8 week full time training with child care to enable women to look after other people's children. Some go on to do full time work in the house of a full time mother and lots of professional women prefer a Tages Mutter who comes to the house and stays there all day, to a nursery.
They started their nursery but had no children full time and were not allowed to have more than 5 babies at a time. The rules in Germany are very strict for the under twos and you don't make much money at it like they seem to do in the UK.
Both young women went back to their original jobs, but the nursery which we all fixed up ourselves, painted and sewed curtains etc. that is still going. It was lovely, warm and cosy with a big safe garden, a kitchen where fresh food was prepared. But some children took a long time to settle in and were given this time even it if it took a month. Some were better off there than at home!
