Sleep
Dummies, thumbs and comfort objects
Non-nutritive sucking is normal and useful, and each option has a different set of trade-offs.
Babies suck for comfort as well as for food, which is a normal reflex present before birth, and the question is only what they suck.
The case for dummies
Reasonable evidence in specific respects.
Dummy use at sleep is associated with a reduced risk of sudden infant death in case-control studies, and several national guidelines mention this.
They provide effective pain relief during procedures in newborns, particularly combined with sucrose.
They soothe, which has value in itself.
They are easier to stop than thumb sucking, since the object can be removed.
The case against
Also real.
Early use may affect breastfeeding establishment, which is why guidance generally suggests waiting until feeding is established, commonly around three to four weeks.
Prolonged use is associated with dental effects — open bite and crossbite — which increase with duration and generally correct if the habit stops by around three years.
Associations with otitis media in some studies.
Possible effects on speech development with very heavy daytime use, where the evidence is weaker.
And night waking to have it replaced, which is a practical rather than medical problem and a significant one.
Using one sensibly
Practical points.
Wait until breastfeeding is established.
Offer at sleep times rather than continuously through the day.
Do not force it on a baby who does not want it.
If it falls out during sleep, it does not need replacing.
Never dip it in anything sweet.
Never attach it to a cord or ribbon around the neck, which is a strangulation risk.
Sterilise for young babies and replace regularly, checking for damage.
Use an orthodontic shape, and consider a one-piece design for safety.
And aim to stop by around twelve months for daytime use and by two to three years entirely, which is when the dental evidence suggests it matters.
Thumb sucking
Different in several respects.
It is always available, which is an advantage at three in the morning and a disadvantage when stopping.
The dental effects are broadly similar and can be more persistent, since the habit frequently continues later.
It cannot be sterilised, though the evidence on infection is mixed.
And it cannot be taken away, which means stopping depends on the child's cooperation and is generally addressed from around four years if it persists.
Stopping
Approaches that work.
For dummies, either gradual reduction — daytime first, then naps, then nights — or a single clear stop with an explanation for older toddlers.
Various rituals work for toddlers: giving them away, exchanging them, or posting them somewhere.
Expect a few difficult nights and do not reverse the decision partway, which teaches persistence.
Choose a settled period rather than during illness, a house move or a new sibling.
For thumbs, at an age where the child can participate: identifying the triggers, providing an alternative comfort, gentle reminders rather than punishment, and where necessary dental input.
Punishment and shaming reliably fail and increase the behaviour.
Comfort objects
Frequently the better long-term answer.
Attachment to a blanket or soft toy is normal, healthy and helps children manage separations and transitions.
Introducing one deliberately is possible: keeping a small flat comforter with the baby during feeds so it acquires familiar scent, and offering it at sleep times.
Safety matters: nothing soft in the cot for infants under twelve months under safe sleep guidance, so comforters generally come in after that, though some small flat comforters are marketed for younger use and guidance varies.
Buy two or three identical ones immediately, since losing the only one is a genuine domestic crisis.
Wash them in rotation so none becomes uniquely irreplaceable.
And do not force a child to give one up on a timetable, since most relinquish them naturally.
The proportionate view
Comfort habits in early childhood are self-soothing, which is a skill rather than a weakness.
The reasonable position is to allow them, to keep the dental timeline in mind, and to avoid making them into a battle — since the anxiety generated by a struggle over comfort tends to increase the need for comfort.
General information only, not medical or dental advice. Follow safe sleep guidance regarding items in the cot, and consult a dentist about prolonged sucking habits.
