Preparing a hospital bag is an important step in the journey of pregnancy. This comprehensive guide provides a list of essential items to pack for the mother, baby, and partner. For the mother, comfortable clothing, personal care items, and important documents are recommended. The baby's essentials include a going-home outfit, swaddle blanket, and an infant car seat. The partner should have a change of clothes, snacks, and entertainment. Additionally, optional items like a pillow, music, and books can enhance comfort and enjoyment during the hospital stay. It's advised to pack the bag by 36 weeks of pregnancy to be prepared for the arrival of the baby.
