The right sleeping bag for your baby: warm, safe, and comfortable

When temperatures drop, you naturally want your baby to be nice and warm at night — but not too warm. A good winter sleeping bag does exactly that: it keeps your little one at the right temperature without the risk of overheating, so you both can sleep peacefully. In this blog, you’ll discover what to look for when choosing a winter sleeping bag and which models at Milk Bar are real recommendations.

Why use a winter sleeping bag?

A winter sleeping bag is specially designed to keep your baby warm during cold nights.
Unlike blankets (which can be kicked off or end up over the face), a sleeping bag stays in place and provides safe and consistent sleeping comfort.

Benefits of a winter sleeping bag:

• Even heat distribution

• No loose blankets in the crib

• Less chance of overheating or cooling down

• Better sleep quality for your baby (and therefore for you too!)
  

What is the TOG rating and which one do you choose in winter?

The TOG rating indicates how warm a sleeping bag is. The higher the TOG, the better the insulation.
For winter, you usually choose a sleeping bag with a TOG rating between 2.5 and 3.5, depending on the room temperature, of course.

Below you’ll find an indicative TOG rating guide, a handy reference:

💡 Tip from Milk Bar: How do you know if a baby is too warm in the sleeping bag? Always use your hand to feel the baby’s neck. Warm and dry = good, clammy = too warm.

Some sleeping bags have removable sleeves, which means they have 2 different TOG ratings.

What size winter sleeping bag does your baby need?

A sleeping bag should not be too big: this keeps it safe and comfortable.
Use this guideline:

• 0–6 months: length 70 cm

• 6–18 months: length 90 cm

• 18–36 months: length 110 cm

💡 Make sure the armholes and neck opening fit well so your baby can’t slip inside.

Frequently asked questions

1. Can my baby still use a blanket in the winter sleeping bag?
No, a winter sleeping bag replaces the blanket. Extra layers can cause overheating. Blankets are also discouraged due to the risk of suffocation.

2. How do I know if my baby is cold?
Feel the neck with your hand.

3. How often should I wash the sleeping bag?
On average 1 to 2 times per week, depending on sweat or stains. Choose mild detergents without perfume.
