Researchers found that bonding with your baby through movement has long-term benefits in terms of kindness.
50% of babies who were bounced in-sync with the person holding them picked up a dropped marker and returned it. Only 30% of those who were bounced out of sync with the person holding them returned it. In-sync babies also reached for the dropped marker more quickly than their counterparts.
So what does this mean? Researchers say skip the baby swings and bouncers every so often and actually hold and move with your child.
