Side-lying breastfeeding can make feeds more manageable when you are recovering from birth, feeding during the night, or simply need to rest your shoulders and back. You lie on your side with your baby facing you, but comfort is only part of the setup. Good alignment, a deep latch, and a safe feeding environment still matter.
How the side-lying breastfeeding position works
In side lying nursing, you and your baby lie on your sides facing one another, usually tummy to tummy. Your baby’s ear, shoulder, and hip should stay in a straight line so the head is not twisted away from the body. Your baby’s nose starts roughly level with your nipple, allowing the head to tip back slightly as the mouth opens wide for attachment.
This position can be useful after a caesarean birth because it keeps your baby’s weight away from the incision, and it may also feel easier after a difficult delivery. For many families, breastfeeding lying down becomes practical for calm night feeds once parent and baby have learned the latch.
Setting up comfortably before you latch
Start by lying on your side on a stable bed or another suitable feeding surface. Support your own head and back so you are not straining your neck or rolling forward. Keep pillows and loose bedding well away from your baby’s face and airway. If you use a pillow under your head, make sure it remains behind your shoulder line rather than drifting toward the baby.
Place your baby on their side facing your breast and bring them close enough that the body stays straight from ear to shoulder to hip. Avoid making the baby turn the head sharply toward the breast; swallowing is easier when the head and body are aligned.
Use your lower and upper arms differently
Your lower arm can rest above your baby, tucked under your own head or pillow, while your upper arm remains free to guide your baby’s shoulders and upper back. Try not to push the back of the baby’s head toward the breast. Gentle support behind the shoulders allows the head to tip back naturally, which can help create a deeper side lying latch.
Getting a deeper side-lying latch
Bring your baby close with the nose opposite the nipple rather than placing the mouth directly over it. Wait for a wide-open mouth, then bring the baby toward the breast so the chin makes contact first. The head should be able to tilt back slightly, leaving the nose free or only lightly touching the breast.
A comfortable latch usually feels like firm pulling rather than pinching or sharp pain. Your baby’s cheeks should look rounded, and you may notice slower, deeper sucking with pauses and swallowing. If your nipple comes out flattened or creased, or pain continues, break the suction gently with a clean finger and try again.

Making nighttime nursing more practical
A nighttime nursing position works best when you prepare before you are exhausted. Keep water and a cloth within reach so you do not have to twist while feeding, and use enough light to check your baby’s position and latch.
For example, if your baby wakes at 2 a.m., bring them onto the bed for the feed, settle into side lying, check that the nose is level with the nipple, and use your upper hand to guide the shoulders closer when the mouth opens wide. Afterward, return the baby to their own safe sleep space.
If you frequently compare side lying with other options at night, breastfeeding positions for newborns and comfortable breastfeeding after a C-section are also useful topics to review.
Side-lying feeding is not the same as safe sleep
Because this position is often used at night, separate feeding from sleep. After feeding, place your baby on their back on a firm, flat, separate sleep surface intended for infants, with no loose blankets, pillows, bumpers, or soft objects.
Avoid feeding on a sofa or armchair when you are so tired that you may fall asleep. These surfaces can create particularly serious risks if a baby becomes trapped or covered. If there is a realistic chance you will doze while feeding in bed, remove pillows, loose bedding, and other items from the baby’s area beforehand, and move the baby back to a separate infant sleep surface as soon as you wake.
When side lying may need extra support
Some babies and parents need hands-on help before this position becomes easy. Ask a qualified breastfeeding professional to observe a feed if your baby repeatedly slips off, makes clicking sounds, cannot stay attached, or feeds for long periods without appearing satisfied.
Seek prompt professional advice if breastfeeding is persistently painful, your nipples are damaged, your baby is unusually sleepy, you are worried about milk transfer, or weight gain is not as expected. Persistent feeding difficulties deserve an individual assessment rather than repeated attempts through pain.
Frequently asked questions
Is side-lying breastfeeding safe for newborns?
It can be an appropriate feeding position for newborns when the baby is well aligned, the airway is clear, and an awake adult is actively supervising the feed. Afterward, the baby should be returned to a separate, firm, flat sleep surface and placed on the back for sleep.
Why does my baby keep losing the latch while side lying?
The baby may be too far from your body, positioned too high or low relative to the nipple, or twisting the neck. Try bringing the whole body closer, keeping ear, shoulder, and hip aligned, and starting with the nose level with the nipple before waiting for a wide mouth.
Do I need to burp my baby after a side-lying feed?
Not every breastfed baby needs to burp after every feed. If your baby seems comfortable, you may not need to interrupt them. If they appear unsettled, swallow a lot of air, or commonly need burping, you can sit them upright briefly after feeding.
Can side lying help after a C-section?
Yes. Many parents find it comfortable because the baby does not rest across the abdomen or incision. Use enough support for your own back and head, and ask for positioning help if moving onto your side is painful during early recovery.
A comfortable position should still feel effective
The best side-lying breastfeeding position lets your body relax while your baby stays close, straight, and deeply attached. Small adjustments often make the biggest difference: nose to nipple, chin approaching first, shoulders supported rather than the back of the head pushed forward, and loose bedding kept away from the baby. Once the feed ends, reset the environment for safe infant sleep. With practice, side lying can become a calm option for rest periods and nighttime feeds.
