Does the chance of having twins really increase if there are already twins in the family, or is that just a myth?

non identical twins can run in families-this means that 2 eggs are released and fertilised by 2 different sperm.

identical are basically a freak of nature as they come from one egg that breaks into two....

thats what i gather but i think if either are in your family you can be at risk!

im 23 and have non id twins age nearly 3-boy/girl and i keep warning everyone in the family lol!!!

by the way there was no twins in my family until i had them!!!
