Should I Stop My Baby Sucking Their Fingers?

Usually, no—you do not need to stop your baby from sucking their fingers. Finger and hand sucking are normal in infancy. Babies use their mouths to explore, practise feeding skills and soothe themselves. If your baby is otherwise comfortable, feeding well and growing as expected, you can generally let them continue.

Rather than repeatedly removing their fingers, respond to what the behaviour may be communicating. Offer a feed when hunger cues are present, comfort your baby when they need closeness, and allow harmless self-soothing when they are settled. Consider gentle intervention only if sucking is damaging the skin, interfering with feeding, causing gagging or continuing strongly as your child gets older and begins to have dental changes.

Why babies suck their fingers

Sucking is a reflex and an important early skill. Some babies suck their hands before birth, and many discover their fingers during the first months of life. Finger sucking may help your baby:

• signal hunger before crying begins
• settle when tired, overstimulated or separated from a caregiver
• relieve discomfort while teething
• explore their body and develop hand-to-mouth coordination
• calm themselves while falling asleep or between sleep cycles

Hand sucking does not always mean hunger. Look at the whole picture. Early hunger cues can include stirring, turning the head, opening the mouth, rooting and becoming more alert. If your baby has recently had an effective feed and appears relaxed, sucking may simply be comforting.

What should I do when my baby sucks their fingers?

Pause and observe before intervening. If your baby is showing hunger cues, offer a breastfeed or bottle rather than trying to delay the feed with a finger or pacifier. Young babies generally need responsive, cue-based feeding rather than a strict timetable. You can find more everyday feeding and development guidance in our baby hub.

If your baby is tired or unsettled, try responsive comfort: hold them close, speak softly, rock them, reduce stimulation or offer an age-appropriate sleep routine. If they remain content with their fingers, there is usually no need to pull the hand away.

Keep your baby's hands reasonably clean with ordinary washing, especially after outings or contact with dirty surfaces. Avoid frequent use of harsh soaps or sanitiser on delicate skin. Keep fingernails short and smooth to reduce scratches. There is no need to sterilise a baby's hands.

Could finger sucking affect feeding?

Finger sucking itself does not usually cause feeding problems. However, it can sometimes mask early feeding cues if adults assume the baby is only self-soothing. Offer a feed when hand sucking appears alongside rooting, increased alertness, lip movements or restlessness.

If you are breastfeeding or chestfeeding, pay attention to effective milk transfer rather than how often your baby puts their hands in their mouth. Signs of an effective feed include rhythmic sucking and swallowing, a comfortable latch, breasts feeling softer after feeds, and your baby appearing satisfied after at least some feeds. Wet nappies, stools and growth should also be appropriate for your baby's age.

A baby who constantly sucks their hands immediately after feeds may still be content, but persistent hunger cues deserve a feeding assessment. A maternal health nurse, midwife, GP or IBCLC can watch a feed and help assess latch, milk transfer, bottle flow, feeding frequency and growth. More support is available through our breastfeeding guidance and bottle-feeding guidance.

What about teeth and jaw development?

Finger sucking during infancy is generally not a reason for dental concern. The likelihood of tooth or jaw changes depends on how long, how often and how forcefully a child sucks, especially once permanent teeth are approaching. Occasional sucking is less likely to cause changes than prolonged, vigorous sucking throughout the day and night.

There is usually no benefit in trying to force a young baby to stop. As your child grows, mention persistent finger or thumb sucking at routine dental visits. A dentist can check tooth position, the bite and the roof of the mouth, and advise whether intervention is needed.

When and how to gently discourage it

For babies, focus on meeting needs and protecting the skin rather than stopping the habit. If an older toddler or child continues to suck frequently, a calm, gradual approach is more helpful than punishment or shame.

• Notice patterns: identify whether sucking happens with tiredness, boredom, anxiety or transitions.
• Offer connection: provide cuddles, reassurance, play or a calming bedtime routine.
• Use gentle reminders: agree on a simple cue with an older child instead of repeatedly scolding them.
• Praise effort: acknowledge times when they choose another way to settle, without turning it into a battle.
• Protect sore skin: keep it clean and dry, and ask a pharmacist or clinician which barrier product is suitable for your baby's age.
• Seek dental guidance: arrange advice if the habit is persistent, forceful or affecting the teeth or bite.

Do not use bitter-tasting preparations, chilli, restraints, tight mittens, bandages or frightening language without advice from a qualified healthcare professional. These approaches can irritate skin, create distress or interfere with a child's ability to communicate and self-regulate. Mittens may also become loose or pose a safety concern if not designed and used appropriately.

Finger sucking, teething and sleep

Babies often chew or suck their fingers more when teething. This may accompany drooling, a desire to bite and tender gums. A clean, cool teething ring and extra comfort may help. Avoid teething jewellery and any item that could break, obstruct breathing or become a strangulation risk.

If your baby falls asleep with fingers in their mouth, you do not need to remove them once asleep. Always place your baby on their back on a firm, flat, clear sleep surface, following local safer-sleep guidance. Finger sucking does not replace safe sleep practices.

When to seek help

Contact your maternal health nurse, midwife, GP, dentist or an IBCLC if finger sucking is accompanied by:

• difficulty latching, coughing or choking during feeds, very long or consistently ineffective feeds
• persistent hunger cues after feeds, fewer wet nappies than expected, poor weight gain or unusual sleepiness
• cracked, bleeding, swollen, hot or oozing skin on the fingers
• white patches, sores or pain in the mouth
• repeated gagging, vomiting or injuries caused by pushing fingers deeply into the mouth
• a persistent, forceful habit in an older child, particularly if teeth, speech or the bite appear to be changing
• finger sucking that seems driven by significant distress or is interfering with daily activities

Seek urgent medical help or contact emergency services if your baby is struggling to breathe, turns blue or unusually pale, is difficult to wake, has a seizure, or appears to be choking. Also seek prompt assessment if a young baby has signs of dehydration, such as markedly fewer wet nappies, a very dry mouth or unusual lethargy.

The bottom line

Finger sucking is a normal and useful behaviour for most babies, so you generally do not need to stop it. Watch for hunger cues, respond with feeding or comfort when needed, care for the skin and let harmless self-soothing continue. Ask for feeding, medical or dental support if the behaviour is causing injury, masking feeding difficulties or persisting strongly enough to affect an older child's teeth or daily life.
