But isn’t it a parent’s job to help with those things that are just beyond your child’s reach? Why is it overparenting to do for your child what he or she is almost capable of?

Think back to when your toddler learned to walk. She would take a weaving step or two, collapse and immediately look to you for your reaction. You were in thrall to those early attempts and would do everything possible to encourage her to get up again. You certainly didn’t chastise her for failing or utter dire predictions about flipping burgers for the rest of her life if she fell again. You were present, alert and available to guide if necessary. But you didn’t pick her up every time.

You knew she had to get it wrong many times before she could get it right.

HANGING back and allowing children to make mistakes is one of the greatest challenges of parenting. It’s easier when they’re young — tolerating a stumbling toddler is far different from allowing a preteenager to meet her friends at the mall. The potential mistakes carry greater risks, and part of being a parent is minimizing risk for our children.

What kinds of risks should we tolerate? If there’s a predator loose in the neighborhood, your daughter doesn’t get to go to the mall. But under normal circumstances an 11-year-old girl is quite capable of taking care of herself for a few hours in the company of her friends. She may forget a package, overpay for an item or forget that she was supposed to call home at noon. Mastery of the world is an expanding geography for our kids, for toddlers, it’s the backyard; for preteens, the neighborhood, for teens the wider world. But it is in the small daily risks — the taller slide, the bike ride around the block, the invitation extended to a new classmate — that growth takes place. In this gray area of just beyond the comfortable is where resilience is born.

So if children are able to live with mistakes and even failing, why does it drive us crazy? So many parents have said to me, “I can’t stand to see my child unhappy.” If you can’t stand to see your child unhappy, you are in the wrong business. The small challenges that start in infancy (the first whimper that doesn’t bring you running) present the opportunity for “successful failures,” that is, failures your child can live with and grow from. To rush in too quickly, to shield them, to deprive them of those challenges is to deprive them of the tools they will need to handle the inevitable, difficult, challenging and sometimes devastating demands of life.

While doing things for your child unnecessarily or prematurely can reduce motivation and increase dependency, it is the inability to maintain parental boundaries that most damages child development. When we do things for our children out of our own needs rather than theirs, it forces them to circumvent the most critical task of childhood: to develop a robust sense of self.

There is an important distinction between good and bad parental involvement. For example, a young child doesn’t want to sit and do his math homework. Good parents insist on compliance, not because they need their child to be a perfect student but because the child needs to learn the fundamentals of math and develop a good work ethic. Compare this with the parent who spends weeks “helping” his or her child fill out college applications with the clear expectation that if they both work hard enough, a “gotta get into” school is a certainty. (While most of my parent patients have graduated from college, it is always a telltale sign of overparenting when they talk about how “we’re applying to Columbia.”)
