The Tulsa parents accused of abusing their one-month-old twin boys pleaded guilty to child neglect and permitting child abuse.
Prosecutors charged Joshua Wray and Clorinda Archuleta in January of 2014 after one of the twins was brought to the hospital with skull fractures, broken bones and bleeding in the brain.
Doctors discovered the other twin also had skull fractures, as well as bleeding in his brain and an eye.
Both boys recovered.
Police said each parent blamed the other for the injuries.
A judge will sentence them next month.
