Creating a safe and comfortable sleep environment for your baby is one of the best things you can do to promote restful nights. But if you’re wondering what actually should be in your baby’s crib and what shouldn’t, look no further! As your baby grows, their sleep space will change, but safety remains the top priority.

Let’s break down exactly what should (and shouldn’t) be in your baby’s crib at each stage.

What should be in your baby’s crib: Newborn to 12 Months

Keep It Simple and Safe

In the first year, less is more when it comes to your baby’s sleep space. The safest sleep environment follows the ABC’s of Safe Sleep: baby should sleep alone, on their back, and in a crib (or bassinet if not rolling yet) with a firm mattress.

At this stage, your baby only needs:

• Firm crib mattress with a fitted sheet (check out my favorite, 100% breathable crib mattress here)
• A swaddle (if they aren’t rolling yet) or a sleep sack
• Pacifier (if they use one)

That’s it! While it may seem too bare, this setup is safest. Loose items in the crib can pose a suffocation risk, which is why things like blankets, stuffed animals, and bumpers should be avoided.

If you’re worried about keeping your baby warm, a wearable blanket or sleep sack is a great alternative to loose bedding.

Introducing Small Comfort Items

Once your baby reaches their first birthday, their sleep environment can shift slightly. While it’s still best to keep the crib relatively simple, you can begin to introduce a few small comforts.

At this stage, many babies benefit from:

• A small, breathable lovey or stuffed animal for comfort
• Firm crib mattress and fitted sheet

Even though it might be tempting to introduce pillows or heavier blankets, it’s best to hold off until they are closer to two years old. Keep in mind that too many stuffed animals or loose items can be a climbing hazard, so if your little one is a crib escape artist, it’s best to keep the space minimal.

What should be in your baby’s crib: 18+ Months

By 18 months, some toddlers remain in a crib, while others transition to a toddler bed. If your child is still in their crib, you can introduce a few more comfort items to help them feel cozy and secure.

• Small pillow (usually recommended after 2 years old)
• Blanket for warmth
• Stuffed animal or lovey (as long as it’s not oversized)

If your toddler is starting to climb out of the crib, it might be time to think about transitioning to a toddler bed. At this point, their sleep space will start to feel more like a “big kid” setup with pillows, blankets, and familiar comfort objects.

Creating the Perfect Sleep Space at Every Stage

No matter your baby’s age, their crib should always be safe, simple, and designed for sleep. Keeping their space free of unnecessary items will not only promote safe sleep habits but will also help your baby learn that their crib is for rest, not play.
