Learn what happens when your baby attaches to the breast and how to tell if it’s going well
Learning to breastfeed can take practice. At first, it might feel like there are so many things to think about, holding your baby and helping them attach. Be reassured, with time and patience, it will become easier and quicker.
If feeding doesn’t feel comfortable, it’s often because your baby isn’t attached well. This page explains what might be happening, what to look for and how you can adjust things for a more comfortable feed.
How babies breastfeed
Breastfeeding is different from sucking on a bottle or straw. To get milk from the breast, your baby needs to take your nipple and a good mouthful of breast into their mouth. Your nipple stretches far back, almost to where the hard and soft palate meet. Your baby’s tongue moves forward and down, then cups the nipple and areola. The tongue and jaw move together to squeeze the breast tissue and draw milk from your breast.
If your nipple doesn’t reach far enough back, it can be squashed against the hard palate. This often causes nipple pain and damage and means your baby may not feed well.
Your baby's mouth is wide open with tongue down and forward. Your nipple is aimed at the roof of baby's mouth. The first point of contact is baby's lower jaw or chin on your areola.
Your baby has a large mouthful of breast. Baby's tongue is forward over the gum, the lower lip is rolled out, the chin is pressed into the breast.
Signs of a good attachment
- Your baby’s mouth is fully open, like a yawn, with a large mouthful of breast.
- Their chin is pressed into your breast.
- Their nose is clear or just touching your breast.
- Their lower lip is turned out (sometimes you can’t see it). The upper lip just rests in a neutral position.
- Their tongue is forward over the lower gum (You may not be able to see this but don’t pull baby away to check).
- More areola is visible above the top lip than below the bottom lip.
- Baby’s cheeks look full and rounded.
- Feeding isn’t painful. Some discomfort is normal at first, but pain should settle once your milk flows.
- You can see your baby sucking and swallowing in a steady rhythm.
Signs your baby may not be well attached
It hurts when your baby feeds.
You hear clicking sounds.
Baby’s cheeks are hollowed as they suck.
Baby slips on and off the breast.
If you notice these signs, gently take your baby off and try again. Place a clean finger in the corner of their mouth and between their gums to break the suction.
Steps to support your baby to latch well (and what to do if it hurts)
Whichever position you choose, make sure you’re comfortable with your back and feet supported.
Hold your baby close
Unwrap your baby and hold them on their side, facing you. Their chest should touch yours, and their head should tilt slightly back so their nose is level with your nipple. Avoid holding the back of their head. Support their neck and back instead.
Encourage a wide mouth
Gently brush your baby’s mouth with the underside of your areola. Wait for a big, yawn-like opening. When this happens, their tongue will come forward over the lower gum.
Bring baby to the breast
Aim your nipple at the roof of their mouth and bring them in quickly. Their chin should touch your breast first, well below the nipple, so they take in a large mouthful of breast.
Check for comfort
Feeding should not hurt. Some early tenderness is normal, but pain that continues means your baby may not be attached well. If your nipples look creased, cracked, or blistered, or if feeding feels sharp or pinching, gently break the suction by placing a clean finger in the corner of their mouth and try again.
Adjust if needed
Small changes can make a big difference. Hugging the lower half of your baby’s body closer can help their chin press into your breast. Check there’s no bunched clothing or an arm between you and your baby.
If your breasts are engorged
Hard, full breasts are difficult for some babies to take into their mouth. Soften your breast before feeding by hand expressing a little milk or use reverse pressure softening.
