Jan. 24 (UPI) -- Researchers have linked flat head syndrome to an increased risk of developing motor, language and cognitive delays.
Flat head syndrome, or positional plagiocephaly, occurs when a baby lays their head on the same side or spot consistently, and develops a flat spot. Flat head syndrome affects one in five babies and the number of incidences rose after Sudden Infant Death Syndrome, or SIDS, guidelines recommended babies sleep on their backs in 1992.
