Sleeping in the Same Room: Room Sharing and Co-Sleeping

Sleeping in the Same Room: Room Sharing and Co-Sleeping

The topic of shared sleep is one of the most debated among parents and professionals. Let's clear up the terms and recommendations.

The definitions

  • Room sharing: the baby sleeps in the same room as the parents, but in their own crib
  • Bed sharing: the baby sleeps in the same bed as the parents
  • Co-sleeping: a general term that includes both situations

When pediatricians say "yes to co-sleeping," they mean room sharing. When they say "no to co-sleeping," they mean bed sharing. The confusion comes from the imprecise use of these terms.

What the guidelines recommend

The American Academy of Pediatrics and the Italian Society of Pediatrics agree:

  • Room sharing: YES -- for at least the first 6 months (ideally 12 months)
  • Bed sharing: with great caution -- there are situations where the risk is too high

Room sharing reduces the risk of SIDS

Sleeping in the same room (but not in the same bed) reduces the risk of SIDS by up to 50%. The reason isn't entirely clear, but it's thought that the sounds of the parent help regulate the newborn's breathing.

When bed sharing is more risky

Bed sharing is strongly discouraged if:

  • Either parent smokes (even if not in the house)
  • Either parent has consumed alcohol, drugs, or medications that cause drowsiness
  • The baby is premature or had a low birth weight
  • You are sleeping on a sofa or armchair (the risk is extremely high)
  • There are heavy blankets, soft pillows, or duvets
  • The mattress is soft or there are gaps between the mattress and the headboard

Falling asleep with your baby on a sofa or armchair is the most dangerous situation of all -- the risk of suffocation is up to 67 times higher than in a crib. If you feel yourself dozing off, move the baby to the crib.

How to make room sharing work

The bedside crib (side-bed)

A crib with a drop side attached to the parents' bed is the best solution: the baby is within arm's reach for nighttime feedings but sleeps on their own surface, safely.

Getting organized

  • The crib should be next to your side of the bed
  • Keep a dim nightlight for feedings without turning on the main light
  • Have everything you need for nighttime changes within reach
  • If you breastfeed, learn to nurse lying down -- then place the baby back in the crib

Many breastfeeding mothers fall asleep unintentionally during nighttime feeds. If you know this might happen, prepare the bed safely: firm mattress, no pillows near the baby, blankets only up to your waist.

When to move the baby to their own room

There's no fixed date. Many families make the transition between 6 and 12 months. Signs it might be time:

  • The baby wakes up at every movement or sound you make
  • You wake up at every breath and murmur they make
  • Everyone is sleeping poorly despite being healthy

How to make the transition

  • Start with daytime naps in their room
  • Use a reliable baby monitor so you feel secure
  • Keep the same bedtime routine
  • Expect a few nights of adjustment

The choice is yours

Every family is different. Some work better with the baby close by, others need their own space. There's no universally right choice -- there's the one that allows everyone to sleep better and safely.

Inform yourself, choose, and don't feel judged. The best choice is the one that works for your family.
