As the father of a "Child of the 90s", you could make a valuable contribution to scientific research. Originally, we asked pregnant mothers to enrol, and in most cases they have remained our first contact in the family.
Now, we would very much like fathers to enrol in the project in their own right – not only biological fathers, but also those who take on the role of parent. Thousands have already done so. If you would like to join them, please read the invitation letter and information sheet (PDF). Then print out the enrolment form, complete it and send it to us at the address on the form.
