Singlets vs Bodysuits: What’s Best for Your Baby’s First Few Weeks?

Those first few weeks with a newborn? A total blur of late-night feeds, adorable yawns, and—let’s be honest—an endless cycle of outfit changes. One minute your baby’s all cozy, and the next, there’s a diaper blowout of epic proportions. Which brings us to a surprisingly important question for new parents: Should you stock up on singlets or bodysuits?

There’s no “one-size-fits-all” answer here. But understanding how each option works—especially when it comes to comfort, convenience, and layering—can make those early days just a little bit easier. And when materials like merino singlets come into play, the game changes entirely.

What’s a Singlet, and Why Do So Many Parents Swear by Them?

Let’s start with the basics. A singlet is a sleeveless, vest-style top that slips over the head and sits close to the baby’s body. It doesn’t snap at the bottom like a bodysuit, which is both a pro and a con depending on your situation.

For many parents, singlets are the unsung heroes of baby wardrobes—especially when made from breathable, natural fabrics like merino wool. Merino singlets, in particular, offer incredible temperature regulation. That means they keep babies warm without overheating, which is perfect for unpredictable newborn body temps.

Here’s the thing: newborns aren’t great at adjusting to environmental changes. So when you pop a soft, moisture-wicking merino layer under their outfit, you’re giving them a bit of a superpower—one that helps keep them dry, cozy, and comfy, even if the weather goes from cool morning to blazing midday.

Bodysuits: The All-in-One Solution (with Snaps!)

Now, bodysuits—you’ve probably already seen or bought a few dozen of these. Short-sleeved or long-sleeved, they cover the torso and snap at the crotch, keeping everything tucked in place. No riding up. No drafts. Less chance of poop getting where it shouldn’t.

They’re often a go-to option for daytime wear, especially when paired with leggings or baby pants. But they can be a little tricky during nighttime nappy changes (those snaps can feel like a puzzle at 3am). That’s where singlets often win out—they just pull right up, no fiddling.

Still, bodysuits do have the advantage of being more “put-together,” which can be helpful for outings or layering under more structured clothes. And in colder climates, long-sleeved bodysuits made from materials like organic cotton or even lightweight wool blends provide added warmth.

Layering: The Real MVP Move

Here’s where things get interesting. You don’t always have to choose between singlets and bodysuits. Many seasoned parents layer them—slipping a merino singlet on first to regulate baby’s body temperature, then popping a soft bodysuit over the top for structure and warmth.

This combo works like a charm in both winter and those tricky in-between seasons. The merino base layer does its magic, while the outer bodysuit keeps everything neatly in place.

Not to mention, singlets make blowouts and spills less of a disaster. Bodysuit gets messy? Just peel it off and leave the singlet on—no need for a full costume change.

So... Which One Should You Stock Up On?

Short answer? Both.

Slightly longer answer? Start with a stash of merino singlets—say, 4 to 6 of them—and a mix of short- and long-sleeved bodysuits. Use the singlets as a base layer, especially in those early weeks when babies are still learning how to stay warm. They’ll stretch with your baby, wash well, and keep them snug without overheating.

If you’re expecting in the warmer months or live in a place like coastal Australia where temps fluctuate like mad, merino singlets are especially helpful. They wick away sweat and keep baby dry when it’s warm, but trap warmth when it’s chilly. A total win-win.

Final Thoughts (Because Baby’s About to Wake Up)

In the end, what matters most is that your baby is comfortable, safe, and easy to dress. Whether you lean toward singlets for their softness and breathability or reach for bodysuits for their coverage and convenience, know this: you’re doing great.

That said, slipping on a soft, cozy singlet—especially one made from merino wool clothing Australia is celebrated for—might just make both your baby and your laundry routine a little happier.

And hey, isn’t that worth it?
