Regarding how parents treat their male and female children from birth through toddlerhood, recent research found that most parents:

A. have continued to refer to their male newborns as strong and their female newborns as weaker and more delicate, much as their own parents did years ago, and continue to treat them differently from birth

B. treat male and female infants similarly until the young child begins to act in gender stereotypical ways due to hormones and then the parents treat them differently

C. treat male and female newborns similarly, but by toddlerhood the parents are dressing the children in gendered clothing and buying gender-typed toys

D. treat their male and female children similarly from birth through toddlerhood, but then the preschools treat the children differently by gender
