The practice of sleeping with an infant is common among parents who want their baby close by at night. Supporters of the method point out that it may help facilitate attachment between a parent and a child. Some negative aspects have been associated with sleeping with an infant, and while it remains a personal choice for parents, many organizations do not promote the practice.
Co-Sleeping
Sleeping with a baby in the same bed as a parent is known as co-sleeping. The practice of co-sleeping is done in many other societies among families who live in small quarters and whose children are not separated in their own room. Proponents of co-sleeping state that it reduces a baby's awake time at night, allowing her to adjust to a nighttime sleep schedule more quickly. Some breastfeeding mothers choose to sleep with their infant for the ease of nighttime feedings.
Hazards
According to the SIDS Network, the risk of sudden infant death syndrome is lessened when a baby sleeps in the same room as his mother, although the Network recommends placing a baby's crib next to the parent's bed rather than sharing a bed with an infant. Co-sleeping may also cause suffocation when a parent rolls over on top of a baby in her sleep. Adult beds have pillows and blankets that are too thick and can smother a baby if they cover his face.
Relationships
Sleeping with an infant can reduce satisfaction and closeness within a marriage. Many parents only have time together while a baby is sleeping, and co-sleeping with a baby eliminates those times. All parents need some time during the day or evening apart from their baby in order to maintain emotional stability. Caring for an infant takes up much of the day and night, and sleeping with an infant further diminishes a parent's personal time.
Transitions
Parents who sleep with an infant may be setting up patterns that prove difficult to break later. As a baby grows, continuing to co-sleep with his parents teaches him that he needs them to help him fall asleep. Children eventually learn to sleep in their own bed, but a child who has slept with his parents since birth may have a difficult time transitioning to his own room.
Protection
For parents who wish to continue sleeping with a baby, several steps can reduce the risk of danger. According to Kids Health from Nemours, parents should put a baby to sleep on her back and ensure there are no pillows or heavy quilts nearby. The bed mattress should fit tightly against the headboard to prevent her from becoming pinned. Adults who go to bed with their baby should refrain from using alcohol or medications that may prevent them from waking easily.
