How you are with your significant other could be heavily influenced by your time as a baby.
University of Minnesota researchers have followed 78 people for more than 25 years.
They looked at relationships as infants, as children, and when the participants became adults.
At that time they also interviewed their romantic partners.
It may come as no surprise that kids who were more secure as babies were in-turn more emotionally attached in their romantic relationships as adults.
But of course, adult relationships are formed by a number of factors, not just how you were as a child.
