This guide is general education that summarizes published research and guidance from groups like the American Academy of Pediatrics, the CDC, and the WHO. It isn’t medical advice, and every child develops on their own timeline. Your pediatrician knows your child; if something feels wrong, call them. In an emergency, call 911.

Yesterday was the routine. Today is the question under it, which some families never need to ask and some ask every night: should we sleep train? Here's what the trials found, and a way to decide that both adults can live with.

## Heart

Sleep training is a choice, not a requirement. The AAP's own advice for this age stops at drowsy-but-awake and a few minutes to resettle, with feeding, changing, and comforting still allowed whenever they're needed ([AAP](https://www.healthychildren.org/English/ages-stages/baby/sleep/Pages/getting-your-baby-to-sleep.aspx)). Night waking at six months is normal, and a baby who wakes isn't broken ([Pennestri et al., 2018](https://pubmed.ncbi.nlm.nih.gov/30420470/)). If the nights are working for you, you can stop reading here.

## Head

The trials are small, and they point the same way. In 43 babies 6 to 16 months old, graduated extinction and bedtime fading improved sleep with no effect on attachment a year later ([Gradisar et al., 2016](https://pubmed.ncbi.nlm.nih.gov/27221288/)). A larger trial followed 326 children who had sleep problems at 7 months and found no lasting harms, and no lasting benefits either, when the children were 6 ([Price et al., 2012](https://pubmed.ncbi.nlm.nih.gov/22966034/)). Whichever way you go, you aren't choosing between a secure baby and an insecure one.

## Body

Two things sit outside the choice. Room-sharing: one US study linked sharing a room at 9 months with about 40 minutes less night sleep and more bed-sharing ([Paul et al., 2017](https://pubmed.ncbi.nlm.nih.gov/28759407/)), but the AAP still recommends room-sharing without bed-sharing for at least the first 6 months because it lowers SIDS risk ([AAP](https://www.healthychildren.org/English/ages-stages/baby/sleep/Pages/a-parents-guide-to-safe-sleep.aspx)); if you move the crib out, the crib stays bare and the back stays down. And setbacks: when separation anxiety brings new night waking later this year, the AAP's advice is to reassure calmly and consistently ([AAP](https://www.healthychildren.org/English/healthy-living/sleep/Pages/separation-anxiety-and-sleeping.aspx)).

### The method talk

- **Time:** 15 minutes, both adults, baby asleep
- **From the guide:** [Sleep: routine first, then decide](https://chorevia.com/learn/6-months#sleep-routine-first-then-decide)

1. Start with the question, not a method: are the nights working for us? If both say yes, write "not now" and a date to ask again.
2. If not, read the two findings out loud: no effect on attachment a year later in 43 babies ([Gradisar et al., 2016](https://pubmed.ncbi.nlm.nih.gov/27221288/)); no lasting harms or benefits at age 6 in 326 children ([Price et al., 2012](https://pubmed.ncbi.nlm.nih.gov/22966034/)).
3. Write the non-negotiables above any method: back to sleep, bare crib, room-sharing to at least 6 months ([AAP](https://www.healthychildren.org/English/ages-stages/baby/sleep/Pages/a-parents-guide-to-safe-sleep.aspx)); feed, change, or comfort a baby who needs it ([AAP](https://www.healthychildren.org/English/ages-stages/baby/sleep/Pages/getting-your-baby-to-sleep.aspx)).
4. Pick one approach you can both do the same way every night; consistency went with better sleep ([Mindell et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25325483/)). Write who does which night.
5. Set a date two weeks out to look at it again.

**Make it work:** If night waking is wearing your family down, ask your pediatrician about the options, including sleep training, before you start ([Price et al., 2012](https://pubmed.ncbi.nlm.nih.gov/22966034/)).

## Watch for

- **Normal:** a baby who protests a new bedtime for a few nights and then settles faster than before. **Call your pediatrician right away** if your baby cries nonstop, or cries when touched or moved, which isn't protest ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Fever)).
- **Normal:** a night feed that stays in the plan; 27.9% to 57.0% of 6- and 12-month-olds didn't sleep 6 or 8 hours straight ([Pennestri et al., 2018](https://pubmed.ncbi.nlm.nih.gov/30420470/)). **Call 911** if your baby is struggling for each breath or has bluish lips or face ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Breathing+Trouble)).
- **Normal:** a run of good nights, then a bad week; separation anxiety can bring waking back ([AAP](https://www.healthychildren.org/English/healthy-living/sleep/Pages/separation-anxiety-and-sleeping.aspx)). **Call your pediatrician right away** if your baby has a fever higher than 104°F (40°C), or looks or acts very sick ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Fever)).

## For you

Whichever you choose, you are not harming your baby. That sentence has a year of follow-up behind it ([Gradisar et al., 2016](https://pubmed.ncbi.nlm.nih.gov/27221288/)) and five years behind it ([Price et al., 2012](https://pubmed.ncbi.nlm.nih.gov/22966034/)), and it applies to the family that trains and the family that doesn't. What the evidence can't tell you is which one you can keep doing at 3 a.m. in week three, and that's the only question that matters.

If you're the partner: if she's the one who hears every wake, your name goes on half the nights before any method goes on the page.
