The mountain wall mural is the centerpiece of this theme, but each piece in the room comes together to create a really gorgeous nursery. The color scheme is classic — cool and calming for a baby's room with lots of creams, whites, grays, and blues. Try it in your own nursery with this mountain blanket ($15) and mountain LED light box decor ($17).

This circus theme is so fun and playful, and we love how they've carried out the theme without going over the top with the color scheme. Look for pieces of decor with elephants, lions, and other circus animals, like this set of fitted sheets ($60 for three).

With unicorns, it can be easy to go a bit overboard with all of the rainbow colors associated with this mystical creature. Instead, try opting for a more subtle palette with pink, white, and hints of gray. A large, plush unicorn ($150) and four-piece unicorn crib bedding set ($140) are just what you need for this theme!

If you love the rustic vintage theme, there's no reason you can't carry it through to your baby's nursery — with a few adjustments. Pick a strong color scheme, like this room's white and soft green, and incorporate vintage elements throughout. Try this 1920s airplane mobile ($64) to hang above the crib!

This pink floral-themed nursery is so gorgeous and well put-together, you can easily adjust it over the years as your child gets older without it feeling dated or inappropriate. The best part about this nursery is the peony wall stickers ($104), which you can easily apply yourself!

The reason this savanna-themed nursery works without feeling gimmicky is its use of neutral colors. The wallpaper is totally appropriate for the theme, but still blends into the background. Grab a set of those cute animal wall art prints ($17 for four) to re-create this in your own home. 

This monochrome setup is one of the easiest to re-create in your nursery, but it's also one with the biggest impact! It works for a baby's nursery because all of the pieces retain their playfulness, despite the lack of color. Look for some cute art prints to hang on the wall and try a four-piece crib set ($160) that does the decorating for you.

This stunning nursery has all of the hallmarks of an adventure theme: a mountain mural, arrows, and a great color scheme. An arrow-print bean bag ($69), some arrow-print crib sheets ($28), and a color scheme with blue, gold, and gray are just what you need to re-create this theme.

The princess theme is pretty ubiquitous for nurseries and children's rooms, but this one does a great job of communicating the theme without being totally pink. By focusing the pink on the wall and some small accents, it feels cozy and comfortable. The swan decor ($12) is a nice touch!

Gray is such a great nursery color, whether your preference is to keep things gender neutral or not. This sky theme is definitely appropriate for boys and girls, and the combination of space, clouds, and star elements creates a really cute look for your baby's nursery. Try these cloud decals ($35) for a similar look!

Who doesn't love a great woodland theme? Foxes, rabbits, deer, and other animals are such cute additions to your baby's nursery.

Disney is a ubiquitous theme for many childhoods, so get your baby started early with a Disney-themed nursery! You can go all out with a four-piece Mickey Mouse crib set ($150, originally $200) or incorporate subtle pieces into the decor like this modern crib sheet ($40) and some Disney-printed wall art ($11 and up).

For the child that you hope never grows up, the Peter Pan theme seems particularly fitting for a nursery. The map art behind the crib makes a great focal point for the room, with lots of other Peter Pan elements scattered throughout. Re-create it for yourself with this gorgeous Peter Pan wall tapestry ($38, originally $44).

One nursery theme that's only going to get more and more popular is the Harry Potter theme! There are so many ways to do this in your baby's room, but we love this Hedwig lamp ($179). This room does the theme right with a dark accent wall, lots of Harry Potter-related pictures, and some additional pieces to make the room feel comfortable and cozy . . . just like Hogwarts!
