My husband is an author and we have identical twins together!
wow thats awesome.  how old are your twins?
My twins are 2 years old. It is interesting to be able to see how genetics play more of a role than environmental factors
Tell me about some of the factors you are talking about.
Being identical, they share 100% of their genes and their personalities are so similar no matter who and what they are individually exposed to.
Do they finish each others thoughts and sentences
Yes they do that even at 2 years old! Twins are the perfect way to study nature vs. nurture.
