some bits of follow-up:
first, a link to the homepage of the private organisation supporting the hotline and the hatch. Beware, it is all German, has no own information on it (yet), and many of the links they provide do not work. Howwever, the links to the press articles work and if you can read German ...
the hatch part of the scheme doesn't work yet for several legal problems. 'Abandoning a person in a helpless state' (your proper legal term for that might be different but you should get the idea) is an offence. And helping to do that is an offence as well. Is a child legally 'abandoned in a helpless state' if she is placed in a bed behind a hatch (with a two minute delay alarm) and is the provider of the beds legally a helper in this offence? This is one of the many problems.
a scheme that is supported by both the rather liberal government and the rather conservative catholic church can#t be that bad.
Adoption is usually quite difficult in Germany as well and most difficult if the biological mother does not say 'yes' from the beginning and is perhaps only 'temporarily unable' to bring up the child herself. Nobody would(should) think that a mother who abandons her child immediately after giving birth and changes her mind two weeks later after her depression has lifted should have no right to bring up her child. But cases in which the b. mother changed her mind after 6 months, two years, 5 years have gone to several courts. I'd hate to be judge in these cases (or foster parent), for I don't know where I'd place the limit.
The overall reaction to the hotline is positive, but the overall reaction to the hatch is 'let's wait and see how it works'.
A serious theme it is, however, I'd like to end with a more funny note: The anonymous handing over has first been introduced in Germany in Amberg. Guess how the scheme was called...

...you should have been able to guess: 'Project Moses'.
