A diaper bag is a specially designed bag used by parents and caregivers to carry essential items for babies and toddlers. These bags typically include compartments for diapers, wipes, bottles, and snacks, making it easier to stay organized while on the go. They come in various styles, sizes, and materials, catering to different needs and preferences. Many diaper bags also feature additional elements like insulated pockets for keeping bottles warm or cool, changing pads for diaper changes, and stroller straps for easy attachment. Some bags are designed to look like regular handbags, allowing parents to maintain a stylish appearance while being practical.
