ST. PAUL — A Hutchinson woman who told police she was stressed out by her child care responsibilities was charged Friday with trying to suffocate her 5-month-old baby in a St. Paul hospital.

Prosecutors charged Katie Elaine Lewis, 24, with assault, child endangerment and domestic assault by strangulation.

She allegedly pinched the baby’s nose closed while covering his nose and mouth. The boy kicked frantically then went limp. Her actions were caught on video.

Ramsey County Attorney John Choi said a hospital staffer stopped the assault, and the infant is now in good condition.
