Keeping your baby in your room for at least six months is the safest way for him or her to sleep. At the same time, the AAP recommends that babies sleep on their own sleep surfaces. For these reasons, the safest bassinet is one that will enable you to room share for as long as possible. Consider your space. Is a compact bassinet the best option, or can you fit something larger? Also think about how you’ll take care of your baby during the night. If you think you’ll prefer nursing in bed, you might want a co-sleeper bassinet to easily transfer baby after feeding and not risk falling asleep with baby in your bed.
All new bassinets must comply with safety regulations under the Consumer Product Safety Commission (CPSC), which outline standards around size, stability and mattress flatness, among others. To be on the safe side, you’ll probably want to purchase a new bassinet rather than finding on second-hand. Also make sure to choose an actual bassinet designed for sleep. Some newborn “holders” or seats do not meet the standards for safe sleep. When in doubt, remember that babies should sleep in a stable structure on a firm, flat surface.
