Although the current study used a novel approach while
investigating childcare and came up with interesting results, it still had
certain limitations. First, the current study examined cognitive
development; however it did not examine the growth over time.
Future studies using growth models should validate if the findings of
this study are consistent using alternative methods. Second, only
maternal stimulation and family SES were used to assess family
context; and difficult temperament and gender were the only
individual level characteristics.
