Pacifiers: When to Start, SIDS, Safe Use and Weaning

Why a pacifier can help

• Sucking is calming, and many babies want to suck more than they need to feed.
• Offering a pacifier when putting the baby down for naps and at night is linked with a lower risk of SIDS, even if it falls out after the baby is asleep. The AAP recommends offering one.
• It's an option, not a must. Some babies never take one, and that's fine.

When to start

• Breastfeeding: the AAP suggests waiting until breastfeeding is firmly established: a comfortable, effective latch and good weight gain. For many babies that's around 3-4 weeks, for some sooner; ask your pediatrician or lactation consultant.
• Formula-fed: no need to wait. You can offer one from the start.
• Offer it after feeds, not in place of a feed. A hungry baby needs milk.

Using it safely

• Offer it at sleep time, but don't force it. If the baby spits it out or won't take it, let it go.
• If it falls out after the baby is asleep, there's no need to put it back in.
• Never coat it in honey (botulism risk under 1), sugar, syrup or anything sweet.
• Never tie it to the baby's neck, wrist, clothing or crib with a string or ribbon. Short clips made for pacifiers are fine for awake time only; remove them for sleep. No pacifiers with attached stuffed toys in the crib.
• Choose a one-piece design that's dishwasher safe and the right size for age. Never make one from a bottle nipple.
• Check before each use: pull on the nipple, and replace it if it's cracked, torn, sticky, or discolored. Have a few spares.

Keeping it clean

• Wash before first use and often with hot, soapy water, or in the dishwasher.
• Rinse it rather than putting it in your own mouth; adults can pass on cavity-causing bacteria.

Ear infections and teeth

• Pacifier use is linked with more ear infections, especially after 6 months. Many pediatricians suggest cutting back to sleep times in the second half of the first year, especially for babies who get frequent ear infections.
• Pacifier use up to about age 2 rarely causes lasting tooth problems. Use past 2-3 years makes bite changes (such as open bite) more likely, so the AAPD and AAP suggest weaning by about 3, and many dentists suggest earlier.

Weaning

• Some families stop before the habit is strong, around 6-12 months; others wait until a toddler can understand a plan, around 2-3.
• Limit it to sleep first, then phase it out at naps, then at night.
• For toddlers: pick a day, talk about it ahead, give it to the "pacifier fairy" or trade it for a small toy, and expect a few rough nights. Don't cut the tip; pieces can choke.
• Praise and comfort rather than shaming.

Thumb and finger sucking

• Normal and self-soothing. It's not a sleep safety risk.
• Most children stop on their own between 2 and 4. It matters more once permanent teeth come in, around 5-6.
• Ignore it in young children; praise not sucking for older ones. Talk to the dentist if it continues past 4 or 5.

Bring it up at the checkup

• Feeding or weight gain seems off after starting a pacifier.
• Frequent ear infections, or questions about teeth from long pacifier or thumb use.
