Night weaning means gradually eliminating your baby’s overnight feeds so they sleep through without eating. Most healthy babies are physiologically capable of fasting 7 to 8 hours by 6 months of age, though the right time to start depends on whether you’re breastfeeding or formula feeding, your baby’s growth, and your family’s readiness. The process typically takes one to three weeks using a gradual approach.
When Your Baby Is Ready
The timeline differs depending on how your baby eats. Formula-fed babies can generally start night weaning from 6 months onward, because formula digests more slowly than breast milk, and nighttime wakings at that age are unlikely to be hunger-driven. For breastfed babies, most guidance suggests waiting until around 12 months, when children are reliably getting enough calories from daytime meals and solid foods to sustain them overnight.
These aren’t rigid cutoffs. A baby who was born premature, is underweight, or has other health concerns may need those night calories longer. The key signal is that your child is eating well during the day, gaining weight steadily, and waking at night more out of habit or comfort than genuine hunger. If your baby nurses for only a minute or two before falling back asleep, that’s a strong clue the feed is more about soothing than nutrition.
Gradual Methods for Breastfeeding Parents
The gentlest approach is to slowly shorten each nursing session. If your baby typically nurses for 10 minutes at a 2 a.m. waking, cut it to 8 minutes for two or three nights, then 6 minutes, then 4, and so on until the feed is brief enough to drop entirely. At each waking, offer comfort through patting, rubbing, or quiet words instead of the breast once nursing time is up.
Another option is stretching the intervals between feeds. If your baby currently wakes at midnight and 3 a.m., start by delaying the first feed by 30 minutes every few nights. Soothe with touch and your voice during that waiting period. Over a week or two, the gap between feeds widens until one or both feeds naturally disappear.
Both methods work on the same principle: you’re slowly breaking the association between waking up and being fed, while still providing physical reassurance so your baby doesn’t feel abandoned.
Night Weaning for Bottle-Fed Babies
With bottles, you have the advantage of being able to measure and reduce the amount precisely. If your baby takes a 5-ounce bottle at night, drop it by about half an ounce every two to three nights. By the time you’re down to an ounce or so, most babies stop waking for it.
Some parents use gradual dilution instead, slowly increasing the ratio of water to formula over a week or two until the bottle is mostly water. At that point, the bottle is no longer rewarding enough to wake up for. Either approach works. Pick whichever feels simpler to execute at 2 a.m.
The 10-Night Method for Co-Sleeping Families
Pediatrician Jay Gordon developed a structured plan specifically for families who bed-share. It works in three phases over roughly 10 nights, and you start by choosing a 7-hour block you want to protect (for example, 11 p.m. to 6 a.m.). Outside that window, you nurse and comfort as usual.
Nights 1 through 3: When your baby wakes during the protected window, you can nurse briefly, but you unlatch before they fall asleep. Then pat, rub, and cuddle them back to sleep without the breast. The goal is to separate nursing from the act of falling asleep.
Nights 4 through 6: When your baby wakes during the window, you cuddle and comfort but do not nurse at all. You still pick them up, hold them, and soothe them back to sleep with touch and your voice. Dropping the feed entirely is the big shift in this phase.
Nights 7 through 10: When your baby wakes, you don’t pick them up. Instead, you pat, rub their back, and talk softly until they settle. No feeding, no lifting.
After these 10 nights, most babies start sleeping through the protected window or waking only briefly before settling on their own. Some need another week of light touch-based soothing before the wakings stop completely.
How a Partner Can Help
If you have a partner who isn’t the one who usually feeds the baby, putting them on overnight duty for a stretch can speed things up considerably. Babies are smart. When they smell milk or feel the familiar chest of the nursing parent, they expect to eat. Removing that cue makes it easier for them to accept other forms of comfort.
The non-feeding partner can pick the baby up, rock or sway gently, pat their back, offer a pacifier, or simply hold them close and talk in a low, calm voice. This works especially well during the middle phase of weaning, when you’ve already reduced feeds but haven’t eliminated them entirely. Having the partner respond to wakings for four or five consecutive nights often creates a noticeable shift in how quickly the baby resettles.
Boosting Daytime Calories
Night weaning works best when your baby isn’t actually hungry overnight, which means making sure they’re eating enough during the day. For babies over 6 months who are eating solids, offer calorie-dense foods like avocado, nut butters (if age-appropriate and no allergy concerns), full-fat yogurt, and iron-rich proteins at meals. A solid dinner and a full feed right before bed help tank them up.
Some parents also add a “dream feed,” a final nursing session or bottle offered around 10 or 11 p.m. while the baby is still mostly asleep. This can bridge the gap to morning and make it easier to drop earlier nighttime feeds first. Once your baby is sleeping through without other feeds, you can phase out the dream feed too.
Why Night Feeds Can Affect Teeth
Once teeth start coming in, prolonged nighttime feeding carries a real dental risk. Milk or formula pooling around teeth during sleep creates an environment where bacteria thrive, and this is a well-documented contributor to early childhood cavities. The risk is highest when babies fall asleep while actively sucking on a bottle or breast, because saliva production drops during sleep and can’t wash away the sugars the way it does during the day. This is one reason many pediatric dentists encourage weaning off overnight feeds once the first teeth appear.
What the First Week Looks Like
Expect the first three to four nights to be the hardest, regardless of which method you choose. Your baby has likely been feeding overnight for their entire life, and that’s a deeply ingrained habit. Protest crying, restlessness, and more frequent wakings are all normal in the first few days. This doesn’t mean it’s not working.
Most families see a clear improvement by nights five through seven. Your baby may still wake once but resettle more quickly, or sleep a longer initial stretch than before. By the end of the second week, many babies are sleeping through or waking only briefly. Some take closer to three weeks, especially if they were waking multiple times per night before you started.
A few practical tips for surviving the transition: start on a weekend or during a stretch when you don’t have early-morning obligations, because you will lose some sleep before you gain it back. Avoid starting during a growth spurt, illness, teething flare, or major change like a new daycare. Pick a calm, boring stretch of life. And once you commit to a method, stay consistent for at least a full week before deciding it isn’t working. Switching approaches mid-stream resets your baby’s expectations and extends the process.
Keeping Nighttime Wakings From Returning
After you’ve successfully night weaned, occasional regressions are normal. Illness, travel, teething, and developmental leaps can all temporarily disrupt sleep. If your baby starts waking again, offer comfort through touch and your voice rather than reintroducing a feed. Most regressions resolve within a few nights if you stay consistent. The one exception is genuine illness: a sick baby who needs fluids overnight should get them, and you can re-drop the feeds once they’ve recovered.
