London - Good mothers really do bring up nicer children, a study suggests.
Teenagers whose moms show them warmth are more likely to help other people and comfort them when they are upset.
Researchers asked more than 300 young people aged 14 to 19 about what kind of mother they had, using measures such as whether she made them "feel better after talking over your worries".
Those with warm moms were more likely to be kind, moral and helpful themselves. Researchers concluded that good mothers pass down their own caring values.
Professor Alexandra Davis, who led the study from the University of New Mexico, said: "We found that mothers who are warm tend to promote moral development in their youths."
