This infuriates me as a working mother. First, this study followed 1,100 children out of approximately 13 million who are in the day care system throughout the United States. Day care is not responsible for a child's home values and discipline. Jay Belsky, one of the principal investigators, was already biased in this study, as he published an article in 1986 that suggested child care posed a risk for developmental problems.
Studies are statistics that can be skewed to the researcher's beliefs.
Instead of always attacking the day care systems, for once let's look at the benefits. When children entered kindergarten 15 to 20 years ago, they first began to learn their alphabet, colors, numbers and shapes. Now, most children who go to a day care at least part time know most of that by the time they are 3 or 4. The day care system is no different from the school system - it needs to be a partnership between facilitators and parents. When parents are not involved, that is where the issue lies.
