Bedside Cosleeper
A bedside sleeper is attached to your adult bed. As long as you adhere to the CSPC guidelines for infant sleeping spaces It's safe.

These guidelines are similar in many ways to crib bedding standards. You can learn more about these guidelines here. When choosing a bedside sleeping device security, comfort and convenience are the most important factors to consider.
Safety
In keeping 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) has gained popularity with a lot of new and expecting parents. The Academy states that room-sharing with a baby is less risky than sleeping in the same bed with a parent because it reduces the chance of Sudden Unexpected Infant Death (SIDS). While the AAP discourages bed-sharing however, it does recommend that co-sleeping be done on a separate sleep surface to minimize the risk of SIDS. This is why the introduction of the bedside cosleeper became so important to many families.
A bedside sleeper is attached to a bed frame for adults. It is a crib like sleeper. The bedside cosleeper allows parents to keep an eye on the baby, and also gives them the option of sleeping in their own bed. The top cosleepers adhere to strict safety standards and are made with durable, high-quality components. Be sure to look for the Juvenile Products Manufacturers Association (JPMA) stamp of approval, which confirms rigorous testing of the product and quality control, to ensure your child's secure cosleeping experience.
cot bedside of a cosleeper is dependent on several aspects. This includes how it's installed and secured onto the mattress of the parent. If the bedside sleeper is not connected to the bed of the parent in a way that blocks the gaps and openings where an infant could be trapped, it could pose the risk of suffocation. It is crucial that the attachment system of a bedside crib be tested to verify it is able to withstand the forces that might be imposed in use, such as a parent rolling onto and off of the sleeper or 25-pound. The attachment system, or the corners on the bedside cosleeper should be exposed to a horizontal force.
The standard for bedside sleeping cribs is based on to the federal consumer product safety standards for bassinets (16 CFR part 1218) which includes the requirements for performance for closed fabric openings. The mandatory requirements in the standard also address head and neck dangers through requiring that after the application and release of 50-lb. The standard also stipulates that following the release and application of 50-lb. It is not permitted to create a gap that is greater than 1.0 in. Read-only copies of the standard can be accessed at ASTM's online Reading Room.
Convenience
While many parents have avoided cosleeping because of fears of suffocation SIDS or the "Ferberization" process that forces children to be in a room by themselves Anthropologists have noted that most primates and mammals as well as those who live in non-Western societies, have regularly coslept. This could be due to the fact that infants are soothed by the familiar voice of their mother, and it can also help them learn to self-soothe.
The best bedside sleepers have an innovative design that is attached on the side of any mattress and can swivel so that you can access it easily for diaper changes or feedings during the middle of the night. Look for a model with adjustable feet that retract to accommodate various mattress sizes. It should also have ample storage space for all of your baby's essentials.
Choose a bedside crib that fits standard crib bedding, so it will be safe to use as your child grows. You may also want to look into a convertible model that could transform into a play yard or deeper bassinet to last for years of use. It folds easily for transport.
Portability
Based on the size of your bedroom, a bedside sleeping system with wheels and/or a light base may be more convenient to move around the house than one that has a heavy wood frame or massive base. The Babybay Bedside Sleeper, HALO BassiNest Essentia and Snoo Smart Sleeper are all equipped with excellent portability features. Adjustable feet that retract to fit platform beds and the legs fold inward for maximum closeness to the mattress and a 100% mesh sidewalls that allow for air circulation without fabric covering the baby's nose or mouth.
The Arm's Reach ClearVue is another popular option that adjusts in 1" increments to fit most adult beds and can also serve as an portable bassinet. It also swivels to give you quick access to the baby to help her relax, nurse her or check on the baby during the night.
