Question

Does it take 18 months for twins to be born? or 9?!

Answer 1

9 months its like a normal pregnancy but with two babies at the same time.

Answer 2

9 months. its always 9 months unless the baby is early or late. but the baby is never more than a week late cuz then they will induce labor. even if it twins it still takes 9 months. and technically you are pregenant for 10 months not 9.
