Before choosing one, keep these safety features in mind:
Firm, flat mattress & surface: Babies should sleep only on their back on a firm, flat mattress with no loose bedding.
Breathable sides: Mesh panels around the bassinet allow airflow and let you see your baby easily.
Sturdy frame: It should be stable and not tip easily if bumped.
Age/weight limits: Most bassinets are safe up to around 15–20 lbs (7–9 kg) and until the baby begins to roll over — usually around 4 months.
