How to Dress Your Baby for Sleep & Weather (TOG Guide)

One of the most common new-parent worries: is my baby too hot or too cold? The simple rule of thumb — dress your baby in one more light layer than you’re comfortable in — covers most situations. Here’s how to nail it for sleep and every season, safely.

Dressing for Safe Sleep

Since loose blankets aren’t safe before 12 months, a wearable sleep sack or swaddle (until baby can roll) is the go-to. Keep the room around 68–72°F (20–22°C). Under the sack, a simple bodysuit or footed pajama is usually right. The biggest risk is overheating, which is linked to SIDS — so when in doubt, dress lighter.

What TOG Ratings Mean

TOG measures a sleep sack’s warmth. Use it with room temperature as a guide:

How to Check if Baby Is Too Hot or Cold

Ignore cold hands and feet — they’re normal and not a reliable gauge. Instead, feel the back of the neck or chest: it should feel comfortably warm, not sweaty or cold. Signs of overheating include sweating, damp hair, flushed cheeks, and rapid breathing. Dress in layers you can add or remove rather than one heavy piece.

Frequently Asked Questions

How do I know if my baby is too hot at night?

Feel the back of the neck or chest — warm and dry is just right; sweaty, damp hair, or flushed cheeks mean too hot. Cold hands and feet are normal and not a sign your baby is cold. Keep the room at 68–72°F and choose a sleep sack TOG to match.

What should a baby wear under a sleep sack?

In a typical 68–72°F room with a 1.0–2.5 TOG sack, a footed pajama or a simple bodysuit is right. Warmer rooms call for just a short-sleeve bodysuit and a lighter (0.5 TOG) sack; cooler rooms call for a footed pajama and a higher TOG.

Can my baby sleep with a blanket?

No loose blankets until at least 12 months, per safe-sleep guidance. Use a wearable sleep sack or, for young babies who aren’t rolling yet, a swaddle to keep them warm without any loose bedding in the crib.
