Problems With Latching On or Sucking: Causes, Signs and Helpful Breastfeeding Tips

Breastfeeding is a natural process, but it does not always happen easily. Some newborns have difficulty latching onto the breast or maintaining an effective sucking pattern. These problems can be stressful for parents, particularly during the first days and weeks after birth when both mother and baby are learning how to breastfeed.

Problems With Latching

A poor latch or weak sucking does not necessarily mean that breastfeeding will not work. There can be several reasons behind feeding difficulties, and identifying the cause early can help parents get appropriate support.

What Is a Good Latch

A good latch allows the baby to take in enough of the nipple and surrounding areola so that milk can be transferred efficiently. The baby's mouth should be wide open, with the chin touching or close to the breast and the lips turned outward.

During effective breastfeeding, you may hear or see regular swallowing. The baby should generally appear comfortable rather than repeatedly pulling away, becoming frustrated or falling asleep immediately after beginning a feed.

For the mother, breastfeeding should not cause persistent or severe pain. Some tenderness can occur during the early days, but ongoing nipple pain or damage may indicate that the latch needs adjustment.

Common Reasons for Latching Difficulties

Several factors can contribute to problems with latching. A baby who is premature, sleepy or unwell may have difficulty coordinating sucking, swallowing and breathing.

Some babies may also struggle because of positioning. If the baby's body is not properly aligned with the breast, maintaining a deep latch can be difficult.

Breast fullness or engorgement can sometimes make the breast and nipple area firmer, making it harder for a newborn to attach. In other situations, a baby's oral anatomy may affect feeding. Conditions such as tongue-tie or other mouth-related differences can sometimes interfere with tongue movement and milk transfer.

Pain, illness or birth-related factors may also affect a baby's feeding behaviour.

Signs Your Baby May Have a Sucking Problem

Parents should pay attention to how their baby feeds rather than focusing only on how long a feeding session lasts.

Possible signs of ineffective sucking include:

  • Difficulty staying attached to the breast
  • Repeatedly slipping off the breast
  • Very weak or irregular sucking
  • Clicking sounds during feeding
  • Long feeding sessions without signs of effective swallowing
  • Frequent frustration or crying during feeds
  • Falling asleep soon after beginning to feed
  • Poor breast milk transfer
  • Fewer wet or dirty diapers than expected
  • Difficulty gaining weight

One sign alone does not necessarily indicate a medical problem. However, several symptoms together deserve attention.

How Parents Can Improve the Latch

Positioning can make a significant difference. Hold the baby close, with the baby's head and body aligned. Bring the baby toward the breast rather than leaning forward and pushing the breast toward the baby.

Allow the baby's mouth to open widely before bringing the baby onto the breast. The nipple should be directed toward the roof of the baby's mouth, helping the baby take in a deeper mouthful of breast tissue.

Skin-to-skin contact can also encourage feeding behaviours. Holding a newborn against the parent's bare chest may help the baby become calmer and show early hunger cues.

It is generally better to respond to early feeding cues such as stirring, hand-to-mouth movements and rooting rather than waiting until the baby becomes very upset.

When Professional Support Can Help

A lactation consultant, midwife, pediatrician or other qualified healthcare professional can observe a feeding session and identify problems that may not be obvious to parents.

Professional assessment can be particularly important when a baby consistently struggles to latch, seems unusually sleepy during feeds, has signs of dehydration, or is not gaining weight appropriately.

If tongue-tie or another oral issue is suspected, a healthcare professional can assess whether it is actually affecting feeding. Not every anatomical variation requires treatment, so decisions should be based on an appropriate clinical assessment.

Protecting Milk Supply

When a baby is not effectively removing milk, the mother's milk supply may be affected. Depending on the circumstances, a healthcare professional may recommend expressing breast milk by hand or using a breast pump while feeding difficulties are addressed.

Expressed milk may sometimes be given to the baby according to professional guidance. Parents should receive individualized advice, especially when a newborn is struggling to feed or has concerns about weight gain.

When to Seek Urgent Medical Advice

Newborn feeding difficulties should not be ignored when they are accompanied by concerning symptoms. Seek prompt medical advice if the baby is difficult to wake for feeds, appears unusually weak, has signs of dehydration, is not feeding adequately, or is not producing an appropriate number of wet diapers.

A healthcare professional should also evaluate significant weight loss or poor weight gain.

Breastfeeding Problems Do Not Mean Failure

Latching and sucking difficulties can be emotionally challenging, but they are common reasons parents seek breastfeeding support. Getting help early can make the experience easier and may prevent small feeding issues from becoming bigger problems.

Every mother and baby pair has a different breastfeeding journey. Patience, proper positioning, observation and professional guidance can help address many difficulties. Most importantly, parents should not feel guilty about asking for help.

Successful infant feeding is ultimately about ensuring that the baby receives adequate nutrition while supporting the health and well-being of both mother and child.
