Babies who have both parents at home for the first few months of life were more proficient at interpreting emotional facial expressions at 14 months than babies who were at home with only one parent. At least that’s what a pretty cool study from Sweden found. And as we all know, when it comes to parenting, the Swedes do everything right (or do they?).

Clara Schmitow, the child psychologist who headed the study, looked at two groups of fifty babies. Half had stayed at home with one parent, half with two. “The study indicates that the sharing of parental leave between parents may affect how the child understands other people’s emotional expressions,” she said. Pretty neat.
