Breast feeding data on 99 children

Description

Data on 99 children born in two hospitals (in Prague and a certain province city in the Czech Republic) in the 90's of the 20th century.

Data are used for several illustrations in the book Regrese by Karel Zvára (Zvára, 2008). Originally, data were obtained by P. Hajná during preparation of her Master thesis with the breast feeding (“kojení” in Czech) habits of Czech mothers as the primary research goal (Hajná, 1995).
