Getting your baby ready for sleep can feel like one of those small but surprisingly stressful parts of early parenting. It’s very common to worry about whether they’re too hot, too cold, or just not quite comfortable enough for a settled night.
The truth is, dressing your baby for sleep doesn’t need to be complicated. Once you understand a few simple principles, it becomes much easier to feel confident at bedtime.
Start with a safe sleep environment
Before thinking about clothing, it’s important to make sure your baby’s sleep space is safe. This gives you a solid foundation to build on.
Your baby should always be placed on their back to sleep, in a clear cot or Moses basket with a firm, flat mattress. There should be no loose bedding, pillows, or toys in the sleep space. Wherever possible, your baby should also sleep in the same room as you for at least the first six months. Once this is in place, you can focus on what they wear.
Keep clothing simple and breathable
A good rule of thumb is to dress your baby in light, breathable layers rather than anything heavy or bulky. Babies struggle to regulate their temperature as efficiently as adults, so layering helps you adjust easily depending on the room temperature.
In most cases, a cotton vest or bodysuit underneath a sleepsuit is enough. Many parents then use a baby sleep bag instead of loose blankets, which helps maintain a consistent temperature throughout the night and reduces the risks associated with bedding in the cot.
Room temperature makes a big difference
The temperature of the room plays a key role in how you dress your baby for sleep. Ideally, a baby’s room should be kept somewhere between 16 and 20°C.
If the room feels cooler than this, you may want to add an extra layer such as a long-sleeved vest or choose a slightly warmer sleepsuit. In contrast, if the room is warmer, you can reduce layers and opt for lighter clothing to avoid overheating.
Small adjustments tend to work better than big changes, as babies can be sensitive to sudden differences in how they’re dressed.
Check the right areas, not hands and feet
One of the most common mistakes parents make is checking a baby’s hands or feet to see if they are warm enough. However, these are often cooler naturally and don’t give an accurate indication of temperature.
A better approach is to feel your baby’s chest or the back of their neck. These areas will give a much clearer idea of how warm they actually are. Your baby should feel comfortably warm, not hot or sweaty. If they feel clammy or overheated, it’s a sign to remove a layer.
Avoid overthinking and over-layering
It’s easy to add “just one more layer” for reassurance, but overheating is actually a greater concern than being slightly cool.
Hats, thick blankets, and heavy bedding should be avoided indoors during sleep. Instead, focus on consistent, breathable layers that can be adjusted if needed. Sleep bags help here because they remove the uncertainty of loose blankets while keeping temperature more stable.
Every baby is slightly different
Even with clear guidelines, every baby will have their own comfort preferences. Some run warmer, others prefer a cooler feel. Things like room airflow, the season, and your baby’s activity levels can all play a part in how they settle.
If your baby is regularly unsettled, sweaty, or waking frequently, it may be worth adjusting their layers slightly until you find a better balance. Small changes are usually enough.
Final thoughts
Dressing your baby for sleep is really about keeping things simple, consistent, and responsive. Once you focus on breathable layers, a safe sleep environment, and checking their chest rather than their hands, it becomes much easier to feel confident in your routine.
There isn’t a perfect formula, but with a bit of observation, you’ll quickly learn what works best for your baby.
