Justifying day care
As if I don’t already feel guilty for putting my son in day care at the tender age of three months, a new study shows that the more time children spend in center-based care before kindergarten, the more likely they’ll fight, disobey and argue, according to their 6th grade teachers.
The increase in problem behavior was slight, but studies like this inspire me to look for the silver lining. And I always return to the same thing: "the hygiene hypothesis," or the belief that early exposure to germs helps the immune system develop properly.
While most children get six to eight infections a year, children in day care bring home twice that number, or about one a month. Day-care settings --or petri dishes, as my pediatrician calls them-- have high levels of indoor allergens and have been shown to incubate and spread antibiotic resistant bacteria.
This sounds like a no-brainer: Keep your children at home! But since most of us don't have that option--63 percent of U.S. children under the age of five spend 37 hours a week in child care--I manage to get through the work day by reminding myself my kids might turn out healthier in the long run.
Some research bears this out. A 2005 study in the British Medical Journal showed that children who attended day care in the first few months of life are less likely to develop leukemia than children who do not, most likely because they were protected from exposure to common infections. Similar associations have been reported for Type 1diabetes and allergies and asthma in children.
Still, even if they have stronger immune systems, is it worth sending them to day care if they’re going to have behavioral issues that persist at least until 6th grade? That, according to the research, published in the March/April issue of "Child Development," is up to the parents.
The researchers involved with the longest and most comprehensive study of child care in the U.S. cautioned that parenting quality was a much more important predictor of child development than the type, quantity or quality of child care.
Ultimately, while quality day care is important, a quality home environment matters more.
