A new Johns Hopkins Study found kids are less likely to get hurt when they're left in the care of their grandparents.
That's compared to daycare, being watched by other relatives, or even by a stay at home mom.
Doctors looked at about three years worth of data on more than fifty-five hundred young kids.
They found when left in the care of a grandparent, kids of working parents are about half as likely to suffer an injury.
The study appears in the journal "Pediatrics."
