What should baby be dressed in to sleep?

How do you go about dressing baby for sleep?

The general advice is to keep it simple ‒ light pajamas, a onesie, a light sleep sack, or a swaddle.

If your baby is in a cold room, you can layer two or more of these options, such as light pajamas under a sleep sack.

Skip the hats, socks, heavy pajamas or sleep sacks, and blankets (or any other loose bedding).

Babies up to 12 months old are surprisingly susceptible to overheating, which is a risk factor for SIDS, and loose bedding can get tangled around their neck or cover their nose or mouth.

How many layers should I dress my baby in at night?

So how many layers should a newborn sleep in?

Ideally, one to two layers are best for dressing baby for sleep at night.

Avoid hats and any sleep sacks with strings of ties, as they can either cause baby to overheat or be a choking concern.

How to dress baby for sleep in a 70-degree room

Some rooms are warmer than others.

Ideally, babies should sleep in a room where the temperature sits comfortably between 68° and 72°F.

By checking how warm their room is using a thermostat or thermometer, you can work out if you need to change how you’re dressing baby for sleep.

You can also check if your baby is too hot or too cold by simply feeling the back of their neck.

If their skin feels hot or sweaty, remove one or more layers of baby sleep clothing.

If they feel colder than usual, you might want to add another layer.

How to dress newborn for sleep

Now, what to dress newborn in for sleep?

If you’ve just welcomed your little one into the world (hi, baby!), you might not be sure what baby sleep clothing is appropriate for newborns.

Stick with something simple like a onesie and add a swaddle.

If they’re too hot, choose pajamas and swaddling cloths with a lighter fabric, light cotton, or muslin.

If they’re too cold, go for a vest underneath their onesie and a warmer swaddling cloth or sleep sack.

Not sure if they’re too hot? They may be squirming a lot or clammy to the touch.

If they’re too cold, they may also be wriggling about or feel a little cold to the touch.

How to dress baby for sleep in summer

It can be confusing when thinking about how to dress a baby for sleep in the summer.

We all love the look of a cozy, bundled-up baby, but it can be dangerous for a newborn to get too hot while sleeping.

On summer nights, dress your baby in light and loose clothing ‒ but not loose enough to cover their face if baby moves in the night.

Usually, a short-sleeved cotton bodysuit or t-shirt with a sleep sack over them is adequate. If the temperature is particularly high, ditch the sleep sack.

Should I swaddle my baby? Is it OK to wrap a baby to sleep?

When it comes to dressing baby for sleep in summer, you may be wondering if you can swaddle them.

Swaddling means wrapping them up like an adorable little burrito for bedtime.

While newborns usually enjoy being swaddled (it replicates being held tightly, helping them feel safe and calm), it’s essential to do so safely during hot weather.

Choose a lightweight and breathable fabric for swaddling to prevent overheating. A wrap made from 100% cotton is ideal during the summer months.

Remember that swaddling is no longer considered a safe option once your baby can roll over, due to the increased risk of suffocation.

If swaddling works for you, you might find that sleep sacks for older babies are an effective alternative once they start rolling over.

How should I dress my newborn to sleep in winter?

When dressing baby for sleep in winter, it can be tempting to wrap them up in layers of blankets to keep them cozy and snug.

However, since babies younger than nine months can’t yet control their body temperature, they mustn’t become too hot.

When dressing baby for sleep during the winter months, a cotton all-in-one sleepsuit with the feet attached (aka, “footy pajamas”) is a great option.

Some sleepsuits even have mittens that are useful during those particularly chilly nights.

Fleece PJs are also a good option for winter since they’re very warm without adding much bulk.

Wool pajamas are also a good ‒ though expensive ‒ alternative.

Can my baby wear a hat for bed?

Since babies cool themselves by releasing heat from their heads, hats and beanies should be avoided all year round for sleep.

Not only can babies easily overheat if they go to sleep wearing a hat, but it can also be a choking or suffocation hazard if it falls off and covers their face.

Keep your baby’s head uncovered during sleep, even during the coldest nights of the year.

Can babies sleep in onesies?

Yes, when dressing baby for sleep, you can opt for a onesie.

Consider what the temperature in the room is ‒ if it’s colder, a thicker onesie or a layer underneath could be a good idea, and if it’s warmer, a lightweight onesie is best.

Should baby sleep in fleece?

Yes, fleece can be a great option for baby sleep clothing, particularly in the winter or colder spring months.

However, fleece can cause overheating in the summer or warmer nights.

If baby’s clammy, it’s too hot for fleece baby sleep clothing.

What should baby wear under fleece sleep sack?

It depends ‒ if it’s a cool night and baby’s feeling cold or sleeping in a cold room, a layer of pajamas or a onesie underneath a fleece sleep sack can help stave off the cold.

But if it’s a warmer night, a fleece sleep sack might not be such a good idea ‒ fleece can trap heat, so even if baby is wearing light pajamas underneath, they could be susceptible to overheating.

Should babies wear socks while sleeping?

Babies can wear socks while sleeping, but only if their feet are cold.

Try lying down with no socks on and see if your feet are cold ‒ if yours are, baby’s will be, too!

Can my baby just wear a sleeper to bed?

If you’re not sure how to dress a baby for sleep, a sleeper or onesie can be a great option.

If it’s on the chilly side, consider adding a sleep sack or swaddle.

If they’re warm, make sure the sleeper is cotton or another lightweight material.

Can baby sleep only in pajamas?

Yes, baby can sleep in just pajamas, as long as they’re comfortable and at the right temperature.

Pair with a lightweight swaddle if baby’s not rolling over yet, to help them stay comfortable and get to sleep quicker.

Can baby wear sleepsuit in sleeping bag?

Yes, if the weather is cold, and baby’s room is a little nippy, it’s fine to dress baby in a sleepsuit and pop them in a baby sleeping bag or swaddle to keep them warm.

If you’re worried about baby overheating, check on them regularly and check their temperature either with a thermometer or by putting your hand on the back of their neck or their tummy ‒ it should be warm to the touch ‒ not hot or cold.

How do you know if baby is cold at night?

When it comes to how to dress a baby for sleep, knowing whether they’re cold or not is key.

But there are some tell-tale signs that baby is too cold in their baby sleepwear:

  • They feel cold on their tummy or the back of their neck.
  • They’re crying and look uncomfortable.

It’s totally normal for baby to have colder hands and feet, but if they’re very cold or changing color, it could be another sign to add another layer of baby sleep clothing.

If you’re really not sure, get a thermometer ‒ between 60.8°F and 68°F is ideal.

And try sitting in baby’s room with a similar amount of layers that baby’s wearing. If you’re cold, baby’s cold.

Is it OK if my baby’s hands are cold at night?

Yes, it’s totally normal for baby’s hands to be colder than the rest of their body ‒ their body is still growing to regulate their temperature all over.

If you think baby might be too cold, check their temperature on their tummy or the back of their neck instead.

How do I know baby is warm enough at night?

The best way to tell if baby is warm enough in their baby sleep clothing at night is to check their temperature ‒ not necessarily with a thermometer, but by putting your hand on their tummy, chest, or the back of their neck.

Their skin should be warm to the touch ‒ about the same temperature as your hands (if you feel warm enough!).

How do I know if my baby is overheating?

Common signs that your baby may be overheating in their baby sleepwear include:

  • They feel hot to the touch.
  • They breathe rapidly.
  • They feel clammy.
  • They have a fever.
  • Their heart rate increases.
  • They are unresponsive.

If you’re worried that your baby is overheating, you can:

  • Slowly remove layers of clothing or covering.
  • Lower the thermostat.
  • Move them to a cooler room.
  • Offer them fluids. If they’re younger than six months, stick to breastmilk or formula instead of water.
  • Wipe them down with a lukewarm or cool cloth. Don’t use one that’s too cold, as this can be too much of a shock to their little systems.

If things don’t improve quickly, contact your healthcare provider as soon as possible.

Knowing how to dress a baby for sleep at any time of the year can be challenging.

However, a home thermostat or thermometer can help you figure out what to dress them in to keep them comfortable no matter the season.

What should a baby be covered with at night?

It’s best to avoid loose blankets when dressing baby for sleep, so their head won’t get covered and they won’t get tangled.

So how do you go about dressing baby for sleep to keep them warm enough without a blanket, especially in the winter months?

The answer is layers.

If baby’s too cold in their onesie at night, add a vest underneath or put them in a sleep sack.

But it’s recommended to avoid blankets altogether until they’re at least 12 months old, due to the risk of suffocation.

The risk of SIDS when dressing baby for sleep

When deciding how to dress a newborn for sleep, you must consider the risk of Sudden Infant Death Syndrome (SIDS).

Overheating can increase the chances of SIDS, so you must dress them in appropriate baby sleep clothing for both the season and temperature of their room.

To lower the chances of overheating, dress your baby in light, comfortable clothes for sleep, slowly increasing the number of layers as the temperature drops.

How much do baby sleep clothes cost?

It’s true, baby clothes can cost a small fortune.

After all, baby grows out of 5 clothing sizes in their first year alone!

But we have a top tip:Get a baby clothes rental subscription from Bundlee to save an average of £1,000 in baby’s first year.

Budget-friendly, space-saving, and it helps fight fast fashion!
