Is it normal for a baby to poop then eat again?

It is quite common for a baby to poop right after or during a feed, which is due to the gastrocolic reflex. While it may seem like the baby is suddenly hungry again, they are often just looking for comfort or are unsettled by the change. You don't necessarily need to offer a full feed again; try rocking, soothing, or simply holding them, as their stomach capacity is small and they may just be adjusting to the movement in their system.
