This study investigates the influence of prenatal mother-child attachment on intrauterine fetal movements and postnatal attachment (0;6 years). 2 questionnaires (The Parental-Fetal Attachment Scale (Cranley, 1981) (13th , 26th and 38th week of pregnancy) and Axis II (Zero to Three, 1994) (6 months post partum)), answered by 92 mothers (18- 38 years) were used to identify the attachment category. Intrauterine fetal activity (head/arm/leg/fetal heart rate in the 13th week of pregnancy ( +/- 1 week) was observed by ultrasound for 5 minutes. For statistical analyses, regression analysis (SPSS-PC+) was used. The results show, that there might be high stability of secure attachment, especially at the end of the second trimenon. Insecure-ambivalent attachment at the end of the first trimenon also remains stable until the age of 6 months. In our sample, there was no significant association between attachment and intrauterine fetal movements.
