On January 30, 2018, the first questionnaire answered by a woman pregnant with twins arrived.

In Hungary, 1.7% of the deliveries produced twins in 2017: 3130 babies out of the 93,063 newborns were twins last year. 3031 of them were twins, 95 triplets, and 4 quadruplets. In the last 45 years, we had fivelings twice: in 1983 and in 1987.

Based on the above numbers, we expect to track the development of over 300 twin babies in Growing Up in Hungary.
