Babies may arch their backs for several reasons, including expressing discomfort or frustration, especially during tummy time or when they're being held in a way that feels restrictive. It can also be a natural reflex as they explore their body movements and develop motor skills. Additionally, arching can indicate a need for attention or a desire to be picked up. Overall, it's a normal part of their developmental process.
