What happens to you when you play with your kids

Parent-child play, when it authentically appeals to the parent, can do grown-ups a lot of good.

(CNN)I'll begin with a confession. Or maybe it's a warning. I like playing with my kids. I don't play with them every day, nor, consistently, every week. But when I do play with them things happen in my brain and body, positive things that counter the oppressive rigidity and repetition of adult life.

This happens through all kinds of play, including family-wide games of charades, pretending plants can talk and impromptu lip-sync and dance parties.
Parents, the same could be true for you.
    There are a lot of bad reasons to play with your kids. It shouldn't be about perfecting skill or achieving a particular outcome, which isn't really play anyway. Or because you feel pressure to be a perfect parent and a perfect parent plays with their kids on a regular basis. Or because they asked you to, and you feel guilty saying "no." Or because your kids can't have fun without you. If that's the case, maybe don't play with your kids until they master the art of independent or sibling play.
      But there are also the good reasons, often overlooked in leisure-phobic culture. Parent-child play, when it authentically appeals to the parent, and works for their schedule, can do grown-ups a lot of good.

      Defining 'play'

      Play isn't any particular activity, so much as a "state of being," explained psychiatrist Dr. Stuart Brown, founder and president of the National Institute for Play and author of "Play: How it Shapes the Brain, Opens the Imagination, and Invigorates the Soul." It deeply engages us, and gives us pleasure, alters our sense of time and place, and the experience matters more than the outcome.
        "Nature has designed us to play in a variety of ways," he said. "We are built to play and are built by play."
        Play with kids can take many different shapes. It can be easily identifiable and include Legos, pretend, dress-up, sports, video games, board games or puzzles. Or it can be a playful approach to an activity that isn't always thought of as playful: baking, gardening, watering the plants or washing the dogs. Or it's spontaneous: making up funny songs in the car or goofing around having a pillow fight in bed on a Sunday morning.
        All of this is highly personal. The parent-child relationship is made up of two individuals with a distinct set of personality traits and desires. The type of play and frequency of play that works in one family will probably look different than what works for another family.
        Right now, each of my sons has a favorite way of playing with me.
        My 4-year-old enjoys imagining that he is the dad and I am the baby. I lay down on the couch -- yep! I don't have to move -- and he pretends to wash the dishes. Every so often I "interrupt" him with a problem that I, the baby, am having. I enjoy crafting the problems, which span from the sorrowful to absurd. ("I'm scared Daddy won't come back from work." "I think a glitter monster is going to cover me in slime.") Even more, I adore hearing what solutions he comes up with to fix my problems. ("Don't worry, baby, the glitter monster is really nice and will give you slime to play with. If it gets on you then you can take a bath!")
        My older son, age 8, and I enjoy making up stories together, which we sometimes do while walking the dog. We have also recently taken up roller-skating as a family, which, apart from my former-hockey-playing husband, involves a lot of goofy trial and error.
        As children get older, play may look more like taking adventures together.
