I happen to have the ability to read the original sources:
-"Social workers will look after the babies for up to three months" - fact: after initial medical care the children come immediately into a foster family, but the final adoption doesn't happen before eight weeks.
- "At least 30 deaths were reported last year, while about 100 were saved after being found in time." original: "There are about thirty foundlings per year in Germany, half of them are found dead."
What the article does not say: The hatch is the last resort and not the prefered method. The main idea to help is a 24 hour free hotline with the offer to help both mother and child, if she prefers that or to give the child away for quick adoption. In that case the mother chooses whether she wants to remain anonymous (even in this case, the usual way of 'handing over' is not the hatch but the offer to come to any place the mother names and to collect the child from woman to woman but with the promise not to ask questions) or whether she wants to be in contact with the foster family. If the mother has given her child away anonymously (via hatch or from woman to woman) she has the option to call a free number to contact the helpers later if she is about to change her mind within 8 weeks.
The hotline telephone part of the scheme has already been introduced in one other German town and finds a lot of positive interest in other towns. I haven't read anything about the hatch part being introduced any other place.
