I am in Bavaria, southern Germany, and I strongly dislike that in Kindergarten Christianity (with a Catholic slant) is taught as absolute truth with no mention whatsoever that other religions even exist. It bugs me and I would like them to tell the Christian stories and celebrate the festivals but also give the same respect to stories and festivals from other religions. no chance of that though as there is no real separation of church and state. I am agnostic I'd say and I want my children to know they can make up there own minds and am unhappy with the "This is the truth" approach. Ho hum, can't have everything. They can do Ethics at school, but by then they've had 3 years of indoctrination.
They don't do nativity plays at Kindergarten (3-6) which covers most of "infant" school as it would be in the UK. My 7 year old (year 2) could have been in a nativity play in the church next to her school, the children were invited via school but but all rehearsals would have been after school with the performance in church on Christmas eve. DD would have liked to be "in a show" - she's a show off performer by nature and has wanted to join a drama group for a while, but there is nothing for her age locally, so there was mild disappointment when she remembered she'd had the letter in her bag 3 days and missed the deadline to sign up! The nativity aspect is not remotely important to her or me though, sorry!
I hated brownies too, so no disappointed about that - there is a similar organisation here but again I'm not that keen on the religious element and would only enrol DD (or her brothers as its unisex) if they initiated it - at the moment my kids are very involved with their football teams, which also have a social life and group identity etc.
I miss lots of things about the UK, but not nativity plays especially, though I don't have any objections to them! I love the fact that here Christmas does not take over school life right from early November, or before - there just isn't time in a 3.5 to 4.5 hour school day!
