## TLDR

- Offering a pacifier at sleep time is linked with lower SIDS risk; it's fine if it falls out or the baby refuses it.
- If breastfeeding, wait until it's well established (often 3-4 weeks). Never dip it in honey or anything sweet.
- Pacifiers can raise ear infection risk after 6 months; aim to wean by about age 3.

## 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.
