Sucking seems to have a soothing and settling effect on babies. Sucking a dummy helps some babies settle.
There’s no evidence that dummies cause serious health or developmental problems in infants. Dentists tend to be concerned about dummy use only when a child’s adult teeth are coming through.
Earache
Some researchers debate about whether dummy use is associated with a higher incidence of middle ear infections. So far the evidence isn’t strong enough to prove either argument.
Early weaning
There’s an association between dummy use and early weaning. But there’s increasing evidence that dummies don’t cause nipple confusion in breastfed babies, and that they aren’t the cause of early weaning. It seems more likely that mothers who are experiencing difficulties with breastfeeding use dummies as a weaning tool.
If you’re experiencing problems with breastfeeding, speak to your maternal and child health nurse or lactation consultant.
SIDS
Some studies have reported a link between the use of dummies and a lowered risk for Sudden Infant Death Syndrome (SIDS). But the reason for such a link is unknown, and not all researchers believe that the research is conclusive.
There are downsides to dummies:
Eventually, your child will have to part with the dummy. Children who’ve had their dummies for some time are likely to be very attached to them. This means that giving up the dummy might not be easy.
To ensure that dummy-sucking doesn’t interfere with feeding, it’s best to offer it only when you can be sure your baby isn’t hungry, such as after or between feeds.
From about six months, your child will be more resistant to infections. This means you need only to wash the dummy with soap and water, rather than sterilising it. Just make sure to squeeze out any fluid that gets inside.
Check the dummy regularly to see if it’s worn or degraded. Babies can choke on any loose bits.
