The short version
Pacifiers are not bad for babies. Paediatric guidelines recommend offering one at sleep time because it is linked to a lower risk of SIDS; wait until breastfeeding is established (3 to 4 weeks), use it for sleep only, start cutting back from 6 months and stop by age 3.
What happened
At six weeks he had cluster-fed from 7pm to 1am, and I was crying on the bathroom floor with the door shut so my mother-in-law wouldn't hear. My husband walked in with his phone and said, quietly, "what if we just try one?" I'd been raised on the idea that pacifiers ruin teeth, ruin breastfeeding and make lazy mothers. I said no. Then I said yes.
He took it, sucked for ninety seconds, and fell asleep on my chest. I sat there feeling guilty and also, for the first time in a month, calm.
The next morning I did what I should have done before: I looked it up properly. What I found surprised me. Paediatricians don't just tolerate pacifiers at sleep time; they recommend them, because babies who go to sleep with one have a markedly lower risk of SIDS. The breastfeeding worry is real but time-limited: the advice is to wait until feeding is established, around three to four weeks, and after that the trials show no effect on how long mums breastfeed. The teeth worry is also real but late: dentists want it gone by three.
So we used it, on purpose and with rules. Only for sleep. Never clipped to his clothes in the cot. Not forced back in when it fell out. And we started cutting it back at six months, when the ear-infection data says heavy use starts to matter.
The one we settled on had a cover that doubled as a steriliser case: drop it in the microwave with a splash of water, three minutes, done. In a diaper bag at a wedding, that case was the difference between a clean pacifier and one that had been on a banquet-hall floor.
He gave it up himself at twenty months, during a cold when his nose was blocked. We never looked back. I still think about that bathroom floor.
A meta-analysis of case-control studies found that babies who used a pacifier for their last sleep had roughly 60% lower odds of SIDS (summary odds ratio 0.39, 95% CI 0.31 to 0.50). The American Academy of Pediatrics' 2022 safe-sleep policy lists offering a pacifier at nap and bedtime among its recommendations, and says you needn't reinsert it once baby is asleep.

Parent summaryFor breastfed babies, the AAP advises waiting until breastfeeding is firmly established, usually three to four weeks. A Cochrane review of two trials (1,228 infants) found that restricting pacifiers made no difference to exclusive breastfeeding at three months in mothers who wanted to breastfeed.

WHO summaryIn a Finnish randomised trial, limiting pacifier use after six months cut ear-infection episodes by 29%. The American Academy of Pediatric Dentistry wants non-nutritive sucking stopped by 36 months; an open bite caused by a pacifier usually corrects itself if use stops before age three.

Philips Avent Ultra Air pacifier with steriliser case, 0 to 6 months (2 pack)
Light, lots of air holes so his chin didn't get soggy, and the case sterilises in the microwave. The case is the reason to buy this one.
Philips Avent Ultra Air, 6 to 18 months (2 pack)
Same design, bigger shield. We bought it when he outgrew the first and started cutting back at the same time.

The storage detail I would check next time
A case was one of the details that mattered in our routine: we dropped pacifiers in cars, malls and a temple. I would check the storage arrangement before choosing one again.

Pacifier clips
Fine on a stroller while you're watching. Never in the cot: the AAP is explicit that nothing should be attached to the baby or their clothing during sleep.
