Question: what is it called when a baby favors one side?
Answer: Infant torticollis (tor-ti-col-lis) is easily diagnosable by tightened muscles on one side of the neck, which leaves your baby's head at a tilt or rotation. Torticollis in infants is common —some studies report that it affects 3 in every 100 babies. Fortunately, in most cases infant torticollis is easily treatable.
