(9)Mothers have been warned for years that sleeping with their newborn infant is a bad idea, because it increases the risk that the baby might die unexpectedly during the night.(10)But now Israeli researchers are reporting that even sleeping in the same room can have negative consequences, not for the child, but for the mother.
    Mothers who slept in the same room as their infants, whether in the same bed or just the same room, had poorer sleep than mothers whose babies slept elsewhere in the house. They woke up more frequently, were awake approximately 20 minutes longer per night, and had shorter periods of uninterrupted sleep. These results held true even taking into account that many of the women in the study were breast-feeding their babies.
    Infants, on the other hand, didn’t appear to have worse sleep whether they slept in the same or different room from their mothers.
    The researchers acknowledge that since the families they studied were all middle-class Israelis, it’s possible the results would be different in different cultures. Lead author, Liat Tikotzky, wrote in an email that the research team also didn’t measure fathers’ sleep, so it’s possible that their sleep patterns could also be causing the sleep disruptions for moms.
     (11)Right now, to reduce the risk of sudden infant death syndrome, the American Academy of Pediatrics recommends that mothers not sleep in the same bed as their babies but sleep in the same room.
    The Israeli study suggests that doing so may be best for the baby, but may take a toll on Mom.
