Mothers of infant twins sometimes ask when they can expect their babies to start interacting with each other. Anecdotally speaking, it appears that this is yet another thing that varies wildly between different sets of twins. It seems quite common for a newborn infant to seem quite unaware of the existence of his or her twin.
My monozygotic daughters, though, always appeared aware of each other. They were separated for 20 days after birth. As soon as J left the NICU to join her twin M at home, she made it perfectly clear that she was aware of her sister, at some level.
I placed both babies on a blanket on the floor, a few inches apart.
After a diaper change, J stretched and wriggled…
…and wriggled and stretched, until she was squished up against her sister. Only then did she fall asleep.
In nearly every photograph I have of M and J together their first few months, their heads are turned toward each other.
They both liked to fall asleep holding onto Sister’s hair. As you might imagine, this didn’t often end well. I took to placing a fuzzy blanket above their heads when they were particularly stubborn, to give them both something to hold that didn’t also pull on the other’s scalp.
When did your multiples seem to become aware of each other?
