Authorities say the Palmerton couple's daughter had no food or water for 16 hours after being left in a car seat in a hot room.
A judge sentenced Kimberly Taschler to 14 months to three-and-a-half years in prison. Husband Jacob Taschler will serve 11 months to two years.
Authorities allege the Taschlers had neglected 11-month-old Kayla even before her death in January 2010.
Both parents cried in Carbon County court on Thursday. Thirty-year-old Kimberly Taschler says she was overwhelmed and didn't seek proper help.
Prosecutors say the mother received a longer sentence because she was home when the baby died and was her primary caretaker.
