What Is Bed Sharing
Bed sharing is when an adult and infant sleep on the same sleep surface, typically a bed. The American Academy of Pediatrics (AAP), the Consumer Product Safety Commission (CPSC), and the National Institute of Child Health and Human Development (NICHD) all recommend against bed sharing for infants under 12 months due to documented risks of sudden infant death syndrome (SIDS), accidental suffocation, and unintentional strangulation.
Research shows that bed sharing increases the risk of SIDS by up to 40 percent when the parent is a smoker, drinks alcohol, or uses sedating medications. The risk peaks between 1 and 3 months of age. Soft bedding, pillows, blankets, and bumper pads create hazards that can obstruct an infant's airway or cause rebreathing of exhaled carbon dioxide, a documented mechanism in SIDS cases.
For adults with sleep disorders, bed sharing with an infant presents separate concerns. A parent with untreated sleep apnea, narcolepsy, or severe insomnia may experience altered arousal responses or fragmented sleep that compromises their ability to respond to an infant's needs or movement during the night.
Safety Guidelines and Recommendations
- Room sharing without bed sharing: The AAP recommends room sharing without bed sharing for at least the first 6 months, ideally the first year. An infant sleeps in a separate crib, bassinet, or play yard in the parent's room.
- Surface requirements: Any sleep surface for an infant must be firm and bare. Adult beds fail this criterion due to soft materials and gaps that pose entrapment risks.
- Medication and substance considerations: Parents taking sedating medications, opioids, or those who consume alcohol should never bed share, as impaired arousal increases SIDS and suffocation risk significantly.
- Sleep disorder impact: If you have diagnosed sleep apnea, the fragmented sleep and oxygen desaturation events associated with the condition affect your awareness and responsiveness. Treating sleep apnea with CPAP therapy before bed sharing decisions improves safety.
Bed Sharing and Parental Sleep Disorders
Parents with untreated sleep disorders face compounded risk. Cognitive behavioral therapy for insomnia (CBT-I) can help a parent manage sleep fragmentation, but this treatment takes time to work. During the acute insomnia phase, reduced sleep quality means reduced parental vigilance. A parent with circadian rhythm disorder who works night shifts and sleeps during day hours may experience microsleeps or reduced arousal capacity that increases risk during shared sleep with an infant.
Polysomnography testing identifies sleep apnea, periodic breathing, and arousal threshold issues that directly affect your safety around an infant. If testing shows moderate to severe sleep apnea (more than 15 apneic events per hour), your physician will typically recommend CPAP treatment before any bed sharing arrangement.
Common Questions
- Is room sharing the same as bed sharing? No. Room sharing means the infant sleeps in a separate crib or bassinet in your bedroom. The AAP supports room sharing as a SIDS risk reduction strategy. Bed sharing means the same surface, which the AAP does not recommend.
- My sleep disorder makes me exhausted. Does this change the recommendation? Parental exhaustion actually increases the risk associated with bed sharing because severe sleep deprivation reduces arousal and responsiveness. Treating your sleep disorder first through proper diagnosis and CBT-I or medical management makes co-sleeping arrangements safer overall.
- What if my infant won't sleep in a separate crib? Frequent night wakings and resistance to independent sleep are common. A pediatric sleep specialist can assess whether your infant has a genuine sleep disorder or typical developmental resistance. Meanwhile, room sharing with a crib maintains the safety standard recommended by major health organizations.
