In this section, Lifelines participants (or their parents) were asked about their own birth and early development. In addition, adult female participants were asked about their reproductive life, including menstruation, childbirth and menopause.
Information on postnatal diet (aside from breastfeeding) can be found here.

A large portion of the questions in this section were asked in the context of two additional assessments, ROAQ and NEXT.
