Many babies develop a favorite side, which can be challenging for both supply and comfort. Try starting every nursing session on the less-preferred side first, when the baby is most hungry and more likely to latch. For night feeds, the side-lying position is often a game-changer, as it can be more relaxing and may help the baby accept the less-preferred breast more easily. If you struggle with supply on that side, you can pump occasionally to maintain stimulation, but don't worry—most babies will still get enough milk even if their preference persists.
