When preparing a nursery for a baby, several essentials are necessary to create a safe and comfortable environment. A crib or bassinet is crucial for sleep, while a changing table provides a designated space for diaper changes. Soft bedding, such as crib sheets and blankets, ensures comfort, and a rocking chair or glider can be helpful for soothing the baby. Additionally, storage solutions like dressers or bins help organize baby clothes and supplies. A baby monitor allows parents to keep an eye on their little one from another room. Finally, soft lighting and decorative items can enhance the nursery's atmosphere.
