A judge on Monday sentenced 20-year-old Jasmine Nicole Francis of Lubbock on two counts of intentional injury to a child. The girl, Ja'niyah, was 5 weeks old when she was injured in February 2011.
Authorities say the girl may have survived because a piece of skull broke off, allowing for relief from brain swelling.
The Lubbock Avalanche Journal reports that the infant's grandmother took her to the hospital after noticing a bump on the baby's head.
Francis, who faced up to 99 years in prison, testified that she tripped while carrying the girl, and the infant's head hit a wall. A jury found her guilty this month.
