Why Is My Baby Gassy at Night? Causes and What Helps
By the Secrets of Tea team. Last updated October 10, 2026.
Babies are gassy at night because they swallow air while feeding and crying, their digestion is still maturing, and lying flat makes gas harder to pass. Slower bottle flow, burping during and after feeds, and a few upright minutes usually help most. Call your baby's doctor about poor weight gain, blood in stool, vomiting or crying that will not settle.
Key takeaways
- Swallowed air, an immature gut and lying flat are the usual reasons gas shows up at bedtime.
- Slow flow nipples, burping halfway and at the end of the feed, and 15 to 20 upright minutes are the first things to try.
- Poor weight gain, blood in stool, vomiting, a fever or crying that will not settle needs your baby's doctor, not home care.
- A warm herbal bottle is a bedtime ritual, not a substitute for those checks.
Why does gas build up by bedtime?
Gas is a normal part of early digestion. Cleveland Clinic notes that babies make gas when they swallow extra air during bottle or breast feeding, crying or sucking a pacifier, and that some babies simply make a little more gas than others.
At night the pattern stacks up. Your baby has swallowed air through a full day of feeds, evening fussiness adds crying and more swallowed air, and a baby lying still has fewer chances to wriggle the gas along than during an active day. Ubie Health describes the same mix: an immature gut that moves food slowly, swallowed air, and lying flat after a feed.

Can the bottle make night gas worse?
Yes. A fast nipple flow makes a baby gulp, and gulping brings in air. Cleveland Clinic suggests angle neck or vented bottles with slow flow nipples, tilting the bottle so the nipple stays full of milk, and stirring formula gently rather than shaking it, so fewer bubbles end up in the feed.
Feed pacing matters as much as hardware. A big last feed at bedtime, or a baby who is already overtired and crying when the bottle arrives, tends to take in more air.
How do burping and positions help?
Burp your baby about halfway through a feed and again at the end, and more often if your baby is gassy. Cleveland Clinic describes two easy positions: over the shoulder, with your baby's head just above your shoulder, or sitting sideways on your lap and leaning slightly forward. Pat the mid back with a cupped hand.
After the feed, keep your baby upright for around 15 to 20 minutes before laying them down, as Ubie Health suggests. If your baby falls asleep before burping, you do not have to force it. Gentle tummy massage and bicycle leg movements while awake are other low effort options.

When should you call your baby's doctor?
Most night time gas is uncomfortable but harmless. Some signs are different. Call your baby's doctor if you see any of these:
- Poor weight gain or refusing feeds
- Blood in the stool or black stool
- Vomiting, especially forceful vomiting
- A fever, unusual sleepiness or limpness
- Crying that is inconsolable or does not settle
- Gas that keeps disrupting sleep, feeding or bowel movements
For a newborn, a baby in the first weeks, or anything that worries you, call first. This article is general information, not medical advice.
Where does a warm herbal bottle fit?
Some parents add a small herbal bottle to the evening wind down. Babies Magic Tea is a caffeine free, USDA Organic blend of chamomile, fennel and cumin in stringless baby bags, traditionally used to soothe little tummies. It is not a replacement for the checks above, and it is worth asking your baby's doctor before starting any herbal tea.
If you go ahead, the label directions are: boil water; stringless baby bag in for 2 minutes, remove; cool; into the bottle 50/50 with formula or breast milk. Bottle only.

Frequently asked questions
Is it normal for a baby to be gassier at night?
Yes, very common. Swallowed air from the day, evening fussiness and lying flat all add up by bedtime. If your baby is feeding well, gaining weight and settles after burping, it is usually normal.
How long should I keep my baby upright after a feed?
Many sources suggest about 15 to 20 minutes before laying your baby down. Ask your baby's doctor about positioning, especially for newborns and for babies who spit up.
Does a gassy baby need to burp every time?
Not every time. Burp halfway and at the end of a feed, and more often if your baby seems gassy. If your baby is asleep and does not burp, let them be.
Can formula or breast milk cause night gas?
Sometimes a baby is sensitive to something in formula or in a nursing parent's diet, but most gas comes from swallowed air. Ask your baby's doctor before changing formula or diet.
When does gas get better?
Many babies grow out of the gassy phase as their digestive system matures over the first few months. If it is not easing, or comes with the warning signs above, call your baby's doctor.
Is Babies Magic Tea safe for a newborn?
Ask your baby's doctor first, especially for a newborn. The tea is made for bottles only, prepared as the label directs.
