All guides/When to introduce a dummy (UK): timing, sleep, and when to stop

Feeding can feel fragile, or someone has mentioned SIDS, and you are weighing whether a dummy helps. This page helps you decide whether to start, how to use one if you do, and when to wind it down. It is not a product roundup.

If you’re new here: Ember is a UK parenting app for babies and toddlers. We write guides like this so you get a clear answer and can get on with your day. When you want practical ideas matched to your child’s age, the free Ember catalogue is there to browse. This page is just about when to introduce a dummy, and when to stop.

When should I introduce a dummy?

Only if you want to, and only after breastfeeding is well established if you are breastfeeding. The Lullaby Trust says that is usually when your baby is around four weeks old. If you are formula feeding, you can introduce earlier, still as a sleep choice rather than all-day use.

Safer sleep comes first either way. According to the NHS, place your baby on their back, in a clear firm flat sleep space, in the same room as you for at least the first six months. A dummy does not stand in for that picture.

Ember’s view: if feeding still feels rocky, protect the feed first. A dummy can wait a few more weeks. If they spit it out, do not force it.

If we use a dummy, how do we use it?

The Lullaby Trust’s safer-use list is short and practical. Treat the dummy as part of sleep, not as a daytime plug.

  • Offer it at the start of every sleep, day and night, not only some naps.
  • Use an orthodontic shape that suits their mouth.
  • If it falls out during sleep, you do not need to keep putting it back.
  • Do not use a neck cord or dummy attachments. They are dangerous.
  • Do not put anything sweet on it, including honey.
  • Do not offer it through awake time as the main soother.

Dummy vs the rest of safer sleep

A dummy is one optional tool. The non-optional bits stay the same whether you use one or not.

Optional if you choose itStill required
Dummy at the start of sleeps after feeding is establishedBack to sleep, clear cot, firm flat mattress
Orthodontic dummy, no cord, no sweet coatingSame room for at least the first six months
Gentle stop between six and 12 monthsNo smoke in pregnancy or around the baby; never sofa-sleep

When should we stop?

Gently withdraw between six and 12 months, according to The Lullaby Trust, to reduce longer-term problems linked with extended use, such as ear infections and teeth drifting out of line. Those longer-term issues have not been shown under one year in their factsheet picture, which is why the stop window sits there.

NHS safer-sleep pages that cover dummies also point to stopping between six and 12 months if you use one. Pick a stretch when life is steady enough, then make nights and naps consistent as you wind down. You do not need a product to replace it. You need the same clear sleep space you already have.

If your baby never liked a dummy, you have not failed a safer-sleep test. Follow the rest of NHS and Lullaby advice and keep going.

What this page is not deciding for you

Judgement stays with you and your health visitor or midwife if feeding or medical advice is involved.

  • Premature babies or medical advice may differ. Follow your unit or paediatrician.
  • If breastfeeding is not established and a clinician has recommended a dummy, ask them how to balance both.
  • You do not need to buy a branded “SIDS dummy.” Clean, orthodontic, used for sleep is the Lullaby picture.
  • Daytime speech and play still need an empty mouth. Keep the dummy for settling to sleep.

A short list you can screenshot

Enough to decide without another midnight scroll.

  • Safer sleep first: back, clear cot, same room six months
  • Breastfeeding? Wait until it is well established (~4 weeks)
  • If using: every sleep, orthodontic, no cord, no sweet coating
  • Do not force if they refuse
  • Plan a gentle stop between 6 and 12 months
  • No dummy product required to “pass” safer sleep

A few quick answers

When should I introduce a dummy?

If you choose to, wait until breastfeeding is well established, usually around four weeks, according to The Lullaby Trust. Formula-fed babies can start earlier. Offer it for sleep, not all day.

When should I stop using a dummy?

Gently stop between six and 12 months, according to The Lullaby Trust and NHS safer-sleep advice that covers dummies. That window helps avoid longer-term ear and dental problems linked with extended use.

Does a dummy reduce SIDS risk?

Some research suggests using a dummy at the start of sleep may help lower SIDS risk. The NHS and Lullaby Trust both treat it as optional alongside the main safer-sleep rules. It does not replace back sleeping, a clear cot, or same-room sleep.

What if my baby will not take a dummy?

Do not force it. Not all babies like dummies. Keep following NHS and Lullaby safer sleep advice. You have not missed a required step.
