Preliminary investigations on the psychomotor development of infants from multiple pregnancies have been carried out.
The psychomotor development in the first six months of life appears to he more similar in MZ than DZ twin partners. It further appears to be rather connected with birth weight than with birth order. The psychomotor development of twins with a birth weight exceeding 2300 g attains, as early as in the first six months of life, a level concordant with the standards established for singletons.
