Littler babies may face bigger sleep problems as they get older.A new study associates lower birth weight and length with sleep disturbances such as breathing problems or nightmares.

The research in the journal Sleep included nearly 300 8-year-olds born healthy and full term. Researchers speculate that smaller birth size could signal alterations in nervous system development which might affect the body's sleep regulation later in life.

Other factors that affect fetal growth, such as prenatal drinking, smoking and chronic stress, may also help set the stage for sleep problems later on.
