Police arrested Jessica Halona in connection to the injuries. Halona has been charged with two counts of third-degree felony child abuse.
The children were treated at San Juan Regional Medical Center and released into the custody of a grandparent.
Police were called to the Motel 6 at 1600 Bloomfield Highway shortly before 1 a.m. Wednesday. People were arguing outside a hotel room when police arrived, Farmington police Lt. Taft Tracy said in a news release.
Witnesses told officers that Halona threw a child across the room, giving the child a bloody nose.
The children also appeared to have old injuries, Tracy said
