This paper reports on a preliminary study of parenting quality, parental stress and child behaviour in families with twins conceived by in-vitro fertilization (IVF) in comparison with families with naturally conceived twins. No differences were found between the types of family in parenting quality or child behaviour. However, parents whose children were conceived by IVF reported greater stress associated with parenting than parents with naturally conceived twins.
