Those are some atrocious infant mortality rates.
1.5-2%, by current developped countries standard is bad indeed, but considering they are supposed to be illiterate near subsistance farmers, this is quite good, historical infant mortality rate were more around 30 to 50% for subsistance farmers.
Mexico's infant mortality rate today is 1.5%, so everything considered, this could be worse, the nazi must have taught them germ theory and there must be some basic medical structure.
