Until they were 11 months old, my twin boys were so nonchalant whenever I'd leave the room that they seemed like a couple of teenagers. As I'd head off to work, the boys would glance my way, then resume chewing on their barnyard animals or playing with their babysitter. They seemed to be thinking, "Eh, catch you later, Mom -- whatever." I figured: Phew! We dodged all the separation-anxiety drama that had stressed out so many of my friends. (Hey, maybe we'd get lucky and bypass the terrible twos, too!)

But then one morning, reality struck big-time. As I opened the door to leave, Ian, the small, scrappy one, began rolling around the floor, wailing as if stricken by food poisoning. Toby, his chubby, gentle brother, clung to my leg, bawling so hard he could barely breathe. I was heartbroken, and totally flummoxed. I had no clue why it was happening or what approach would be easiest on the boys.

"Separation anxiety can happen almost overnight, which makes it shocking to parents," says Sara Abbot, associate director of the Family Resource Counseling Center in Los Angeles. What's more, it's often not just a one-time, babyhood phase for many kids. The tears and fears related to being apart from Mom or Dad can resurface in the toddler and preschool years, posing new challenges for parents and warranting different
solutions. As disheartening as that may sound, it can be very helpful to remember that separation anxiety is completely normal, even healthy. "From the earliest years of life, we should want children to encounter ordinary adversity because it's practice for building resilience," says Aaron Cooper, Ph.D., coauthor of I Just Want My Kids to Be Happy! Why You Shouldn't Say It.... Fortunately, there's plenty you can do to minimize your child's angst, as well as your own, along the way.

the first strike: babyhood

Though the timing can vary from child to child, separation anxiety typically first hits around 8 months, when babies suddenly grasp that their parents exist apart from them, says Abbot. "Literally, it's like, boom! They understand you can leave." They don't, however, understand that you're coming back. This anxiety may last several weeks, or even a few months, until your child realizes that you're not, in fact, abandoning him for life -- you're just going to the bathroom. 

how to get through it:

start early  By 6 months, introduce your baby to other regular caregivers, such as relatives or a babysitter. "Your child needs practice being away from you, hopefully well before preschool," says Alex Barzvi, Ph.D., clinical director of the New York University Child Study Center's Institute for Anxiety and Mood Disorders. "You want someone else to hold and talk to your kid a little differently." These experiences may minimize her anxiety later on when you're not around.

keep your goodbye short  A quick "Bye, James, see you this afternoon!" is ideal. "Prolonging the departure gives your child the idea that there's something to be afraid of," Barzvi says. But here's the really tough part: Try not to let the sobbing lure you back. Reappearing after you've left only gives your child incentive to cry harder and longer next time. 

match your body language to your words  "Your child can sense your confidence as you walk out the door," Cooper says. Flash a smile, give a cheerful wave. You'll be faking it, of course, but she won't know that yet. She'll just know that you feel good about who she's with -- and she can, too.

avoid sneaking off  Parents often dash out the door when the child isn't looking, hoping -- understandably! -- that this will preempt a meltdown. "But that's tricking your child, and it can break your child's trust in you," Barzvi says. Instead, first ask your caregiver to redirect your child's attention right after you leave with a favorite toy, a game of peekaboo, or some new music (whatever), then say your quick goodbye.
