Bedside Cosleeper
A bedside cosleeper attaches to your adult bed. If you stick to the CSPC guidelines for sleeping spaces for infants It's safe.
These guidelines are similar to crib bedding standards. You can read more about these guidelines here. When selecting a bedside sleep device safety, comfort, and ease of use are the primary factors to consider.
Safety
In accordance with the American Academy of Pediatrics' recommendation that infants are in the same room as their parents, cosleeping (a practice also referred to as bed-sharing) is becoming popular with many new and expecting parents. The Academy says that sharing a room with a baby is less risky than sleeping in the same bed as a parent because it reduces the risk of Sudden Unexpected Infant Death (SIDS). While the AAP disapproves of bed sharing, it does recommend that co-sleeping be done on a separate sleep surface to minimize the risk of SIDS. The development of the bedside crib was important for a number of families.
A bedside sleeper is attached to a bed frame designed for adults. It is an equivalent of a crib-style sleeper. The bedside cosleeper allows parents to keep an eye on their little one and allows parents the freedom of a bed while keeping their child close to them. The top cosleepers adhere to strict safety standards and are made using durable, high-quality materials. To ensure the safety of your child ensure that you look for the Juvenile Products Manufacturers Association stamp of approval. This is a sign of rigorous testing and quality control.
The security of a cosleeper for the bed depends on several aspects, including the manner in which it is put up and attached to the parent's bed. If the bedside cosleeper is not attached to the parent's bed in a way that prevents the gaps and spaces where an infant can become trapped, it could be the risk of suffocation. It is crucial that the attachment system used for the bedside sleeper be tested in order to ensure that it can withstand forces that are imposed during use, for example the parent moving on and off the sleeper. horizontal force applied to the attachment system or corners of the bedside cosleeper.
The standard for bedside sleepers includes by reference to the federal consumer safety standard for bassinets and cradles (16 CFR part 1218) that includes performance requirements for enclosed openings with a fabric-side. The standard's mandatory requirements tackle the issue of head and neck entrapment by requiring that, after the application, release 50 lbs. horizontal force at the attachment system and the corners of the bedside sleeper a gap that is greater than 1.0 in. It is not permitted to create a gap larger than 1.0 in. ASTM's electronic Reading Room offers read-only versions of the standard.
Convenience
Many parents are reluctant to cosleep because they fear being suffocated or SIDS or because it's a "Ferberization" which requires children to be in a room by themselves. However, anthropologists have observed for a long time that many primates, mammals and people from non-Western cultures sleep regularly. This is because babies are soothed by hearing their mother's voice. They can also learn to self-soothe.
The best bedside sleepers feature an innovative design that is attached to the side of any bed and can be swiveled for easy access for middle-of-the-night feedings or diaper changes. Find a model with adjustable feet that retract to accommodate different sizes of mattresses. It should also include an ample storage area to store everything your baby needs.

Select a bedside sleeper that fits the standard crib bedding so that it can be used safely as your child grows. Consider a model that is convertible and can be used as a play area or a more substantial bassinet. It will last for a long time.
Portability
A bedside cosleeper that has wheels or a light base is more portable than one that has a heavy wooden frame or base. The babybay Bedside sleeper, HALO BassiNest Essentia and Snoo Smart Sleeper all come with excellent portability features. funny post retract to accommodate platforms and the legs fold inward to give the most comfortable closeness to the mattress and a sidewalls made of 100% mesh that let airflow without fabric covering baby's mouth or nose.
