Will dummies help or hinder feeding and speech development?
I was recently chatting with some new mums about the facts and myths behind dummies. If you think about it, dummies have a long history. The first mention of them was in Germany in the 1500s but excavations of ancient burial sites show evidence of clay dummies similar to the ones we have today. In fact, in the 2nd century, doctors recommended putting honey in feeding dummy contraptions to promote the healing properties of honey. Which explains why today, we still find mothers putting honey in baby bottles and on dummies. Please don’t do this, we now know that honey can contain clostridium bacteria which in fact can cause infant botulism when babies under 12 months are given contaminated honey. As babies get older, their immune and digestive systems get better at handling these strains of bacteria.
Here’s a “teething ring” advertisement from a Sears Roebuck & Co catalogue (1)
Should I give my baby a dummy?
Well, it depends on when and why you are giving it.
There is research to support the use of dummies in preterm infants. Premmie babies who were bottle fed and given dummies were shown to perform better with bottle feeding and develop a more effective nutritive suck when feeding (2). The use of dummies was also found to help transition to full feeds, these babies showed less defensive behaviours during tube feeds and spent less time in fussy and active states during tube feeds (3).

If you are planning to breastfeed your baby, it is recommended that you establish breastfeeding before offering a dummy (about 4 weeks). The reasoning behind this is that sucking produces more milk so you want your baby to suck as often as he likes on your breast so your body can maximise its breastmilk production in the early weeks. Attachment and positioning is really important to establish a good suck and minimise any nipple damage so speak with a midwife or Lactation Consultatant if you need some assistance. If your baby is having difficulty with his suck- swallow and breath coordination then it might be beneficial to also speak with a Paediatric Speech Pathologist (like us at “Let’s Eat! Paediatric Speech Pathology”) who specialise in this suck-swallow coordination process.
If you are planning on bottle feeding your baby then it is up to you when you offer it. Try to pick one that looks similar to the bottle teat you are using. It is best if you don’t create a sleep association with your baby and his dummy as it might create long term sleep and settle issues (related to sleep cues) for you down the track. There is also another thought that babies who have sensory integration issues (ie constantly need to suck to calm their body systems) may need dummies to provide them with this sensory input to calm their system. From personal experience, I know that with a baby who has reflux, giving a dummy helps them to keep their milk in their stomachs and therefore reduces the risk of inflammation from constant regurgitation and vomiting.
What about the impact of dummies on speech development?
In the first 12 months, a baby is learning to use his mouth to experiment with sounds to coo and then eventually babble. The development of these babbling sequences are very important and so if you give your baby a dummy, make sure to limit its use so they have plenty of opportunities to babble.
There is a very interesting research article called “the impact of prolonged (meaning beyond 18 months) pacifier use on speech articulation’ (ref 4) that summaries the risk of dummies on speech development. Mainly long term use will distort the development of ‘s,z,sh,ch,t,d,n’ sounds eg ‘sun’ might sound like ‘thun’. This is because the dummy encourages the forward-backward movement of a baby’s tongue which results in the above sounds being pushed forward. If your baby thumb-sucks, then it is likely that their thumb sucking will have the same impact on their speech development. So again, limit the dummy use up until 12 months (and definitely by 18 months) and start implementing strategies to wean and eventually get rid of the dummy around this time.
What other effects will the dummy have?
The article mentioned above (ref 4) details the risk of increased ear infections with dummy use as well as long term dental problems. Thumb sucking and the dummy encourage an “open bite” malocclusion in infants which may require orthodontic work down the track. I spoke with a lovely Paediatric Dentist in Newcastle about dummies (and if you need a recommendation, drop me a line) who said that if a baby was seeking sucking and would reach for his thumb then she would rather they suck on a dummy because you can get rid of the dummy but you can’t with a thumb! She also recommended not letting a baby suck on a dummy over night because the impact of a dummy on dental development was related to the time the dummy was in his mouth – and overnight was therefore the longest.

So where does that lead you as a parent?
The bottom line? Too much of anything isn’t a good thing! If your baby is seeking the sensory comfort of a dummy, then try to limit its use. My mother calls the dummy a “shusher” – which I think is a perfect analogy, it keeps your baby quiet. Being a mum means I know firsthand that although you make know the theory; practically, you need to get through the day, sleep deprived, exhausted and emotional, the dummy may be your salvation for the first 6 months. Just try not to rely on it too much, let your baby cry (without shoving the dummy in first) so they can communicate with you that they are tired/hungry/want attention so you can learn the differences between their cries and respond to them appropriately (and nurture appropriately e.g. cuddle, massage etc.). And always have a weaning dummy plan ready so you don’t get to the stage where the dummy puts your baby to sleep or keeps them settled – you already have other strategies (like a sleep routine) to do that.
How do I wean a dummy?
If you are struggling with weaning the dummy from your child, try developing a plan with your family, write it down, put some support in place (eg your mum might come up for the week to help out) and be consistent, even if it means waking up and night and re-settling your baby, know that each step forward you take is one step closer to weaning the dummy. This will not only help your child’s long term sleep, speech and settling strategies but dental health as well.
