Which position is most comfortable while breastfeeding?

Back and arm pain while breastfeeding sitting down is very common — it's usually caused by leaning toward the baby or holding your arm unsupported for a long time. One of the most comfortable positions is the "football hold" (or "clutch hold"): you hold the baby beside you, facing your body, tucked under your armpit; in this position your arm goes forward rather than back, so your shoulder and back carry much less strain. Another is the "cross-cradle hold": you support the baby's head with the hand opposite the breast you're nursing from, resting that arm under your back — this distributes your arm's weight toward the front rather than onto your back. In both, it's very important that your back is fully against something and your feet are flat on the ground; a pillow or folded towel under your lower back can provide support. If the pain doesn't ease after 2-3 tries, seeing a lactation consultant or physical therapist would be a good idea.
