Breastfeeding while lying down, usually called the side-lying position, lets you feed your baby while resting on your side in bed. It’s one of the most practical positions for nighttime feeds, recovery from a cesarean birth, or any time you simply need to rest. The technique takes a little practice to set up, but once you and your baby find your alignment, it can make feeding significantly more comfortable.
How to Set Up the Side-Lying Position
Start by lying on your side in bed with a pillow under your head and one or two pillows tucked behind your back for support. The back pillows help you stay comfortably on your side without rolling backward. Make sure the pillow under your head isn’t so large or so close to your baby that it could cover their face.
Tuck the arm you’re lying on under your head or pillow. This keeps it out of the way and gives your baby a clear path to your breast. Your free arm is your working arm: use it to guide your baby’s head toward your nipple and support their back once they latch.
Lay your baby on their side facing you so you’re tummy to tummy. This is the most important alignment cue. Check that your baby’s ear, shoulder, and hip form a straight line, with no twisting at the neck or torso. A twisted position makes it harder for them to swallow and harder to maintain a deep latch.
A small rolled-up blanket placed behind your baby’s back can help keep them from rolling away from you while feeding. Remove it as soon as the feed is over.
Getting a Good Latch on Your Side
The same latch principles apply lying down as sitting up, but gravity works differently, so positioning matters more. Bring your baby’s nose level with your nipple before they latch. This encourages them to tilt their head back slightly and open wide, which leads to a deeper, more comfortable latch where more of the areola is in their mouth.
Use your free hand to shape your breast if needed, gently pressing behind the areola to make it easier for your baby to get a mouthful. Once they’re latched and feeding steadily, you can relax that hand. You’ll know the latch is working if you feel a tugging sensation without sharp pain, and you can hear or see your baby swallowing.
If the latch feels shallow or pinchy, break the seal by sliding a finger into the corner of your baby’s mouth, reposition, and try again. It often takes two or three attempts in the beginning. That’s completely normal.
Switching Sides
When you need to feed from 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. Some parents find it easier to stay on the same side and offer the top breast by leaning slightly forward over the baby, though this can feel awkward and is harder to sustain for a full feed. Rolling over is generally more comfortable and gives you better alignment.
Why This Position Helps With Rest
Side-lying breastfeeding is popular for nighttime feeds because it lets you stay horizontal. Research from the Academy of Breastfeeding Medicine found that breastfeeding mothers who fed lying down and shared a sleep surface woke frequently to feed but fell back asleep more rapidly and were awake for shorter stretches than mothers who got up for feeds. In one laboratory study, 94% of mothers who routinely fed in bed reported getting “enough” sleep, compared with 80% of mothers who fed in a separate space. Breastfeeding mothers overall slept about 40 to 45 minutes more per night than formula-feeding mothers.
This position is also valuable after a cesarean delivery because it puts no pressure on your incision. And for parents dealing with back pain, engorgement, or simple exhaustion, lying down removes the work of holding your baby’s full weight in your arms.
Keeping Your Baby Safe in Bed
Feeding your baby lying down often means feeding in an adult bed, which introduces safety considerations that don’t exist in a chair. The American Academy of Pediatrics recommends that infants sleep on their backs in their own sleep space (a crib, bassinet, or portable play yard) with a firm, flat mattress, a fitted sheet, and nothing else: no loose blankets, pillows, stuffed toys, or bumpers. They specifically advise against sleep on couches, armchairs, or recliners, where suffocation risk is highest.
If you plan to feed lying down and then move your baby to their own sleep space afterward, the main precaution is staying awake until the feed is done. Many parents find it helpful to set a quiet alarm or keep a dim light on.
La Leche League’s Safe Sleep Seven
For parents who may fall asleep while feeding, La Leche League International outlines seven conditions designed to reduce risk. They advise that the breastfeeding parent should be a nonsmoker, sober and unimpaired, and breastfeeding. The baby should be healthy, placed on their back, and lightly dressed. Both parent and baby should be on a safe surface.
A safe surface means a firm, flat mattress with no gap between the mattress and headboard, wall, or side rails where a baby could become trapped. Remove unused pillows, heavy comforters, stuffed toys, and anything that could dangle or tangle near the baby. Keep pets off the bed. Check that the distance to the floor and the landing surface below wouldn’t pose a danger if the baby rolled to the edge.
Avoid feeding while lying on a sofa, recliner, or any soft, sagging surface. These carry the highest suffocation risk because babies can become wedged into cushions or between a parent and the back of the furniture.
Common Challenges and Fixes
If your baby keeps slipping away from the breast, the rolled blanket behind their back may not be snug enough, or you may need to scoot your body closer. Your baby’s mouth should be at breast height without either of you straining. If you find your baby is too low, try placing a thin folded towel or receiving blanket under them to raise their head slightly.
Parents with larger breasts sometimes find the lower breast difficult to offer because it presses into the mattress. Placing a small rolled towel under the breast can lift it enough to clear your baby’s nose and make latching easier. For the upper breast, leaning forward slightly or tucking a pillow under your top arm can help bridge the gap.
If you feel like you’re hunching forward or curling around your baby, your back support isn’t doing its job. Add another pillow behind you, or switch to a firmer one. Your spine should stay relatively neutral so you’re not sore after the feed.
Newborns sometimes need more head support than older babies to stay in position. Using your lower arm to cradle their head (instead of tucking it under your own pillow) works well in the early weeks, though it can get tiring during long feeds. As your baby grows and develops more neck control, you’ll likely shift to the arm-under-pillow setup, which is more sustainable.
