If you have a very strong letdown, your baby might struggle at the breast, leading to fussiness, gas, or spitting up. Try expressing a small amount of milk on a towel before latching the baby to manage the initial flow. Nursing in different positions, such as the football hold or reclining while feeding, can also help the baby control the flow better. If the issue persists, consider consulting a lactation consultant to assess your baby's latch and ensure they are feeding comfortably.
