In families with two working parents, fathers may have more impact on a child’s language development than mothers, a new study suggests.
　　Researchers recruited 92 families form 11 child care centers before their children were a year old, interviewing each to establish income, level of education and child care arrangements. Overall, it was a group of well-class families, with married parents both living in the home.
　　When the children were 2, researchers videotaped them at home in free-play sessions with both parents, recording all of their speech. The study will appear in the November issue of The Journal of Applied Developmental Psychology.
