**Short answer:** A baby with a cold usually sleeps badly because a blocked nose makes it hard to breathe, feed, and settle. The safest things that help are saline drops and gentle suction before feeds and sleep, a cool-mist humidifier, plenty of fluids, and lots of comfort. Keep your baby on their back on a flat, bare sleep surface, without propping or inclining it, and don't give over-the-counter cough and cold medicines to children under 2; the FDA warns they can cause serious side effects.

With cold season starting, I've put saline drops and a bulb syringe in the drawer of Adam's nursery, and I read up on what actually helps a stuffy baby sleep before I needed it at 2am.

Key takeaways

- **Clear the nose before feeds and sleep:** saline drops, then gentle suction with a bulb syringe.

- **Cool mist, not warm:** the FDA suggests a cool-mist humidifier and advises against warm-mist ones.

- **No cold medicines under 2:** the FDA doesn't recommend them, and labels say not under 4.

- **Flat and on the back:** don't prop the mattress or let your baby sleep in a swing or car seat. The AAP says any incline over 10 degrees isn't safe for sleep.

- **Expect 7 to 10 days:** the AAP says cold symptoms should go away slowly over this time.

## Why won't my baby sleep when they have a cold?

Mostly because of the stuffy nose. Young babies rely heavily on breathing through their nose, especially while feeding, so congestion makes it harder to feed, settle, and stay asleep. Many babies with colds also wake because they're uncomfortable, coughing, or a bit feverish, and some want to be held more than usual.

The AAP lists the usual cold symptoms in children as a runny nose, sneezing, low fever, poor appetite, sore throat, cough, fussiness, and slightly swollen glands in the neck. It says the symptoms should go away slowly after 7 to 10 days. The NHS adds that symptoms can last longer in young children. So you're looking at around a week or more of broken nights, which helps to know going in.

## How can I help my congested baby sleep?

Clear the nose right before sleep and feeds, and make the room comfortable. These steps are based on the FDA's advice on easing cold symptoms in children:

- **Use saline drops.** The FDA says saline nose drops or sprays keep nasal passages moist and reduce stuffiness. Put a few drops in each nostril while your baby is lying on their back, and wait a moment for the mucus to loosen.

- **Suction gently.** The FDA says a bulb syringe works well for children under 1, with or without saline. Squeeze the bulb first, place the tip just inside the nostril, then release. Clean it after each use.

- **Time it well.** Clearing the nose shortly before a feed and before putting your baby down helps most.

- **Run a cool-mist humidifier.** The FDA says it can ease breathing by reducing nasal congestion, and warns not to use warm-mist humidifiers. Keep it out of your baby's reach and clean it as the manufacturer directs.

- **Offer plenty of fluids.** Offer breast milk or formula often; small, frequent feeds may be easier while their nose is blocked. Toddlers can also have water.

- **Don't overdress.** A baby who feels hot or feverish needs lighter layers, not extra blankets. See [how to dress your baby for sleep](/how-to-dress-baby-for-sleep-by-temperature/).

Saline drops, then gentle suction, before feeds and sleep can make breathing easier.

## Can I raise the head of the crib or let my baby sleep upright?

No. It's one of the most common tips online, but it isn't safe for babies. The AAP's 2022 safe sleep guidance says any surface that inclines more than 10 degrees isn't safe for a baby to sleep on, and that babies should sleep on their back on a firm, flat surface. Wedges and sleep positioners are on the AAP's list of products to avoid.

That also rules out letting a sick baby sleep in a swing, bouncer, or car seat for the night. You can hold your baby upright while they're awake, and it's fine to cuddle them during a rough patch. If they fall asleep on you, move them to their crib or bassinet. Our post on [baby sleep in a swing or car seat](/baby-sleep-in-swing-car-seat/) explains why sitting devices aren't safe for sleep.

Sick nights are when exhausted parents are most likely to fall asleep with a baby on a sofa or armchair, which is particularly dangerous. If you're very tired, put your baby down in their own safe sleep space. Keep it simple: on the back, firm and flat, a fitted sheet only, no pillows, wedges, or rolled towels, and in your room. Don't use vapor rubs or essential oils on babies without asking your pediatrician first.

## Can I give my baby cold medicine to help them sleep?

Not cough and cold medicine. The FDA doesn't recommend over-the-counter cough and cold medicines for children younger than 2, because they could cause serious and potentially life-threatening side effects. Manufacturers voluntarily label them "do not use in children under 4 years of age," and the FDA also urges parents not to give homeopathic cough and cold products to children under 4. The NHS says decongestants shouldn't be used by children under 6.

- **Fever or pain relief:** if your baby is uncomfortable with a fever, ask your pediatrician or pharmacist whether a fever reducer is appropriate. They'll give a dose based on your baby's weight. Never give aspirin to children.

- **Antibiotics:** the AAP notes they have no effect on viruses, and colds are viral.

- **Honey:** never for babies under 12 months because of the risk of botulism. After the first birthday, ask your pediatrician about honey for a cough. See [can babies have honey?](/can-babies-have-honey/)

**What the research says:** the warnings against cold medicines in young children are firm and based on safety reports of serious side effects. The evidence for home remedies is weaker. Saline, suction, and humidifiers are recommended by the FDA and widely used because they're low-risk, but there are few good trials showing exactly how much they improve sleep. They're sensible comfort measures, not cures.

Even with a stuffy nose, keep your baby on their back on a flat, bare surface, with no wedges or incline.

## Will a cold undo my baby's sleep habits?

Usually only for a little while. Comforting a sick baby more than usual is the right call, and most babies go back to their old patterns within a week or so of feeling better. A few tips once they're well again:

- **Return to your usual routine** as soon as your baby is clearly better, with the same bedtime steps in the same order.

- **Drop extra night feeds gradually** if they crept in during the cold, once your pediatrician is happy your baby is eating and gaining well.

- **Watch for a second problem.** A baby who seemed to be improving and then wakes in more pain, pulls at an ear with a new fever, or gets worse after a few days may have an ear infection or other complication. Our guide to [ear infection vs teething](/ear-infection-vs-teething/) can help you tell the difference.

Call your local emergency number if your baby:

- is struggling to breathe: breathing very fast, nostrils flaring, skin pulling in between the ribs, or grunting with each breath

- has blue or gray lips, tongue, or nails, or pauses in breathing

- is very hard to wake, floppy, or hasn't had a wet diaper in 12 hours

Call your pediatrician if your baby is 3 months old or younger and has any sign of illness, has a temperature of 38°C (100.4°F) or higher under 3 months, or, in older children, a temperature over 38.9°C (102°F), ear pain, unusual fussiness or sleepiness, a runny nose lasting more than 10 to 14 days, a daytime cough lasting more than 10 days, or isn't getting better each day. See our guide to [baby fever and when to call the doctor](/baby-fever-when-to-call-doctor/).

## Frequently asked questions

**Q: Can my baby sleep in my bed when they have a cold?**

The AAP recommends against bed-sharing for babies, and that doesn't change during illness. Room-sharing, with your baby in their own crib or bassinet next to your bed, makes it easy to check on them.

**Q: Is it OK to let my sick baby sleep longer than usual?**

Yes, extra sleep is normal when babies are ill. But if your baby is so sleepy they're hard to wake or won't feed, call your pediatrician.

**Q: Should I wake my baby to suction their nose?**

Usually not. If they're sleeping and breathing comfortably, let them sleep. Clear the nose before the next feed instead.

**Q: Does a steamy bathroom help?**

Some parents sit with their baby in a steamy bathroom for a few minutes before bed. It's a comfort measure, not a proven treatment; never leave your baby alone and keep them well away from hot water.

**Q: How do I tell a cold from RSV?**

RSV often starts like a cold. What matters is how your baby is breathing and feeding. Fast or labored breathing, pauses, or poor feeding need urgent medical advice, whatever the virus.
