Side-lying breastfeeding means you and your baby both lie on your sides, facing each other, while your baby nurses from the lower breast. It’s one of the most comfortable positions for nighttime feeds, post-cesarean recovery, or any time you’re exhausted and need to rest while feeding. Getting the alignment right takes a little practice, but once it clicks, many parents find it becomes their go-to position.
How to Set Up Your Position
Start by lying on your side with a pillow under your head. Tuck a firm pillow behind your back for support so you don’t roll backward. You can bend your lower arm up under your pillow or extend it above your baby’s head, whichever feels more natural. Place another pillow between your knees to ease pressure on your hips and lower back.
Your baby lies on their side facing you, with their whole body turned toward yours so their chest, belly, and hips are all pressed against you. This full-body contact is important. If only their head is turned toward the breast while their body faces the ceiling, they’ll struggle to latch and may pull off repeatedly. Think of it as belly to belly: their nose should be level with your nipple before they latch.
Your baby’s feet should rest against your body rather than dangling in open space. Flexing their hips slightly, almost in a curled position, helps keep them stable and close. You can use your upper arm or hand to gently hold their back and keep them snug against you.
Getting a Deep Latch on Your Side
With your baby’s nose lined up at nipple height, let their chin touch your breast first. This encourages them to tip their head back slightly and open wide, which leads to a deeper latch. Their mouth should cover a large portion of the areola, not just the nipple tip. If you feel pinching or sharp pain, the latch is too shallow. Break the seal with your finger and try again.
You can use your upper hand to shape your breast, holding it so it doesn’t press down on your baby’s chin. Some mothers find it helpful to roll very slightly forward to offer the breast, then ease back once the baby is latched. Leaning too far forward, though, can cause neck and shoulder strain over time.
If your baby has trouble reaching the lower breast, try placing a small folded towel or thin blanket under them to raise their height slightly. This works especially well for smaller newborns who need a little boost to align with the nipple.
Keeping the Area Safe
Many parents fall asleep during side-lying feeds, which makes the setup of your sleeping surface matter. La Leche League International outlines seven criteria for safer bedsharing while breastfeeding:
- No smoking in the home or outside
- Sober adults with no alcohol or sedating medications
- Breastfeeding day and night
- Healthy, full-term baby
- Baby on their back when not actively nursing, face uncovered
- Light clothing on baby with no swaddling
- Safe surface with a firm mattress, no extra pillows near the baby, no stuffed animals, no heavy or loose blankets, and all gaps firmly filled with rolled towels
The American Academy of Pediatrics recommends that infants sleep on their backs in their own separate sleep space. If you plan to nurse side-lying and return your baby to a bassinet afterward, clearing the bed of loose bedding near the feeding area still reduces risk during the feed itself. Keep pillows away from your baby’s face, and avoid feeding on a couch or armchair where a baby could become wedged between cushions.
Why This Position Helps After a C-Section
Side-lying is one of the best positions for parents recovering from a cesarean birth because there’s no weight or pressure on the incision. Sitting upright with a baby across your lap can press directly against the suture line, which is painful in the early days. Lying on your side avoids that entirely. Research published in the Journal of Caring Sciences confirms that side-lying puts less pressure on the surgical site compared to seated positions, making it a practical choice during those first difficult weeks.
It’s also useful for anyone recovering from a long or physically exhausting labor, an episiotomy, or significant fatigue. You can rest your body while still feeding effectively.
Switching Breasts Without Sitting Up
To offer the other breast, you have two options. The simplest is to roll over to your other side and reposition your baby to face you again. If that feels like too much movement, especially after surgery, you can lean forward slightly and offer the top breast instead. This takes a bit more maneuvering and may require tucking a rolled blanket behind your baby to keep them close enough, but it saves you from having to flip over entirely during nighttime feeds.
Burping After a Side-Lying Feed
Babies still swallow some air during side-lying nursing, so burping afterward is worth the effort. The easiest low-disruption method is to gently lift your baby to your shoulder while you’re still lying down, patting their back softly. Or sit up slowly and hold them upright against your chest.
Keeping your baby upright for 10 to 15 minutes after a feed helps prevent milk from coming back up. This is especially important for babies who spit up frequently or have reflux. If your baby seems uncomfortable or fussy mid-feed, pause to burp them before continuing. Babies who are relaxed and feeding calmly may not need as much burping, but it’s still good practice to try after every session.
When Side-Lying May Need Adjustments
Babies with reflux can sometimes struggle with side-lying because they spend the feed in a flat position. Lying flat is one of the factors that contributes to infant reflux, since gravity isn’t helping keep milk down. If your baby has significant spit-up or seems uncomfortable after side-lying feeds, you can try propping your upper body on a wedge pillow to create a slight incline. Holding your baby upright for longer after the feed also helps.
Very young newborns, especially those under a few weeks old, sometimes have trouble maintaining a deep latch in this position simply because they’re small and still learning to coordinate sucking and swallowing. If you’re finding it frustrating in the early days, try it again in a week or two. Many babies who struggled initially latch beautifully in side-lying once they’ve grown a bit and gained more head control.
If you notice your baby consistently latches better on one side than the other while lying down, that’s normal. Breast shape, nipple direction, and your baby’s preference all play a role. Practicing on the trickier side during daytime feeds, when you’re more alert and patient, can help both of you figure it out without the pressure of a middle-of-the-night session.
