Summary
This study is a prospective, multicentre, interventional cohort study in children with Prader-Willi Syndrome (PWS) over 4 years (no treatment administered). The duration of the preceding OTTB3 study is 26 weeks. An untreated cohort of children with PWS will be included at an age of 2 years and followed up until an age of 4 years. Regarding the untreated cohort, children with PWS born in France and too old to be recruited in OTBB3 trial, principally those who were born within one year before the start of OTBB3 trial, will be offered to participate in this study. Infants born later who couldn't be included in OTBB3 study will be also offered to participate.

- Treated cohort: the child participated in the OTBB3 study and is aged 16±4 months at inclusion,
