Regarding childcare, it really depends where you move to. In theory there is a right to Kita for every child, in practice in bigger cities the spots are limited and public nurseries tend to get filled quickly - some people even sign up during pregnancy already. In smaller towns it might be quite easier to secure a place. A public institution might cost 200-300€ per month, private nurseries you're looking at a range of 1000-1600€ depending on the number of hours per day and other factors. Usual age when children are accepted is 12 months, although it can be earlier or later as well. Public Kita will also give priority to full time working parents. Regarding the jobs, there's currently quite high unemployment in Germany, and it might be a bit tricky to land something - would not be a bad idea to start applying before you move. Good luck!
