ABSTRACT
Twin pregnancy is not a simple one, firstly because, of course, not only are there of course 2 foetus which make special medical care necessary, but also because a birth of twins has social, economic and psychological impacts under families, peculiar to this kind of pregnancy (high rank pregnancies are not tackled in these recommendations - or such a little thing - but the whole description for twin pregnancy is valid or even increased for triplets or more pregnancies). It has been found useful to inform the medical profession of these specificities. These pages are the expression of a presence of listening and of demands since more than 30 years beside French multiple births families. The setting up in France of recommendations of clinical practices for the follow up care of twin pregnancies has been a demand of multiple births parents for a long time. They hope of these recommendations will result in optimal care of the specific risks of twin pregnancies therefore a more favourable prognosis for future twins and thus avoid as much as possible an overload of the impact on the family unit.
