Can Babies Sleep on Flannel Sheets?


Flannel sheets are known for their soft, warm cuddle factor, making them tempting for a baby’s crib.

But are they truly safe and suitable for little ones?

Quick Answer

No. The safest sleep environment for a baby is a firm mattress with a fitted sheet and no loose bedding, pillows, or stuffed animals.

The Allure of Flannel

Flannel’s appeal lies in its napped fabric, which traps warm air, creating a snug sleeping environment.

This can be especially beneficial during colder months when maintaining room temperature might be challenging.

Additionally, the soft texture feels gentle against delicate skin, potentially promoting relaxation and better sleep.

Potential Concerns with Flannel

Here are some potential concerns with using flannel sheets for babies:

1. Overheating

The biggest concern with flannel is its insulating properties. Babies are particularly susceptible to overheating, which can increase the risk of Sudden Infant Death Syndrome (SIDS).

2. Breathability

Tightly woven flannel can restrict airflow, making it harder for your baby to breathe comfortably. This is especially concerning for young babies whose breathing reflexes are still developing.

3. Suffocation Risk

Loose flannel sheets or blankets pose a suffocation hazard. Babies can become entangled in the fabric, restricting their airway.

4. Potential for Allergies

While less common, some babies may have allergies to flannel, particularly if it contains synthetic fibers or dyes.

Tips for Safe Use Flannel Sheets

If you’re still keen on using flannel sheets for your baby, here are some key safety tips:

Temperature is crucial

Only use flannel sheets in cool weather when your baby needs extra warmth. In warmer months, opt for lighter, more breathable fabrics like cotton.

Dress baby lightly

When using flannel sheets, dress your baby in thin, lightweight pajamas to avoid overheating.

Monitor room temperature

Keep the room temperature cool (around 68-72°F) and ensure good air circulation. Use a room thermometer to monitor temperature regularly.

Snug fit is key

Choose a well-fitting sheet that hugs the mattress tightly and doesn’t bunch up. Avoid using loose or oversized sheets.

Regular checks

Frequently check on your baby throughout the night to ensure they are comfortable and not overheating. Feel their neck or back to gauge their temperature.

Ditch the extras

Remove any other loose bedding, such as blankets, pillows, or stuffed animals, from the crib to minimize suffocation risk.


When it comes to your baby’s sleep environment, safety is paramount.

While flannel sheets may seem inviting, the potential risks outweigh the benefits in most cases.
