Several positions are commonly used in neonatal care: 1. Supine Position: The baby lies on their back. This position is generally recommended for sleep to reduce the risk of Sudden Infant Death Syndrome (SIDS). 2. Prone Position: The baby lies on their stomach. While not recommended for unsupervised sleep, this position can be beneficial for preterm infants under close supervision to improve oxygenation. 3. Side-Lying Position: The baby lies on their side. This can be useful for feeding and to prevent aspiration in babies with gastroesophageal reflux. 4. Upright Position: Holding the baby in an upright position can help with burping and reduce reflux after feeding.
