When you're dressing a newborn, every extra second matters at 3am. The fastening on your baby's romper for newborn outfits can be the difference between a smooth change and a full meltdown, for everyone involved. Zip suits and snap suits each have loyal fans, and both styles are available at Baby Goes Retro. Here's what actually matters when you're choosing between them.
Why Fastening Type Matters More Than You'd Think
Newborns need changing up to 12 times a day. That means 12 opportunities for a fiddly fastening to slow you down, scratch tiny skin, or wake a just-settled baby. The right fastening makes a romper for newborn easy to get on and off without lifting the baby fully upright, without wrestling with poppers in the dark, and without anything pressing on the belly button stump in those first fragile weeks.
Beyond nappy changes, fastenings also affect how a suit fits as babies grow. Some styles accommodate a bulky nappy better than others. And if your baby is in and out of a carrier or pram, the fewer the fiddly bits, the better.
The Case for Zip Suits
A zip suit opens in one smooth motion. One hand can hold the baby still while the other pulls the zip down. No counting poppers, no misaligning snaps in dim light, no second-guessing which direction the fastening runs. For night changes in particular, zip suits are hard to beat.
The best zip onesie newborn styles feature a two-way zip, meaning you can open from the bottom for a nappy change without unzipping the whole suit and exposing the baby to cold air. DUNS Sweden's zip suits are a great example: GOTS-certified organic cotton with bold Scandi prints and a smooth two-way zip that genuinely works with one hand.
The DUNS Sweden Radish Tender Shoots Green Zip Suit is one of the most popular baby zip suits at Baby Goes Retro. The radish print is playful without being overwhelming, and the GOTS-certified organic cotton is gentle on newborn skin. Sizes run from 6-9 months through 12-24 months.
The DUNS Sweden Radish Pale Dogwood Pink Zip Suit is a beautiful soft pink option with the same GOTS-certified organic cotton and easy zip opening. It's a popular choice for gifting and works well paired with an organic bodysuit underneath for cooler mornings.
The DUNS Sweden Multi Radish Rouge Red Zip Suit brings bold colour with the same practical zip opening. All DUNS Sweden zip suits are made from GOTS-certified organic cotton and ship Australia-wide from Victoria.
The Case for Snap Suits
Snap suits, also called popper suits or lap neck suits, have their own advantages. The most important: a snap suit newborn style with a lap neck opening can go over the baby's head without any zipping at all. The envelope fold at the neckline means the suit can go down over the body rather than over the head, which is very useful if there's a nappy blowout and you don't want to drag a soiled suit across the face.
Snap suits also tend to be slightly easier to size up: the body can be left unsnapped at the crotch for a little extra length, buying you an extra week or two before sizing up. They're often available in smaller newborn sizes, including 0-3 months, where zip suits are less common.
Frugi's organic rompers and lap neck suits are a good example of snap-style done well. The GOTS-certified organic cotton is soft from the very first wash, and the snap placements are thoughtfully designed for practical early nappy changes.
The Frugi Into the Wild Gift Set includes a snap-style romper in GOTS-certified organic cotton, perfect for newborns from 0-6 months. It comes gift-packaged and ships Australia-wide from babygoesretro.com.au.
What Parents Actually Use
Most parents end up with both. Zip suits become the go-to for nights, quick changes, and days when you're out and about. Snap suits are useful for the very early weeks when newborn sizing is fussier and in warm weather when a light snap bodysuit is enough on its own.
If you're building a newborn wardrobe and can only pick one style, zip suits win for practical day-to-day dressing from around 6 months onwards. For the newborn stage specifically (0-3 months), snap bodysuits layered under a light suit give you the most flexibility. Browse the full range of organic baby rompers at Baby Goes Retro to see both styles side by side.
Brands That Do Both Well
DUNS Sweden excels at zip suits: their two-way zips are genuinely practical and the GOTS-certified organic cotton holds its softness wash after wash. The Kite Organic Bunny Zip Suit is another strong option, with integrated scratch mitts on a zip-open sleepsuit that's ideal for newborns. Frugi produces excellent snap-style rompers and lap neck suits in GOTS-certified organic cotton, with thoughtful fit details that make early nappy changes much easier. All brands stocked by Baby Goes Retro are GOTS-certified and ship Australia-wide.
Frequently Asked Questions
Are zip suits safe for newborns?
Yes, zip suits are safe for newborns as long as the zip is covered by a fabric flap or has a protective tab at the top to prevent contact with skin. All DUNS Sweden and Kite zip suits stocked at Baby Goes Retro have covered zips and are made from GOTS-certified organic cotton, free from harsh chemical finishes.
What is better for night time nappy changes, a zip suit or a snap suit?
A zip suit is generally better for night changes because it opens in a single motion with one hand. A two-way zip is even more useful, as you can open just the bottom of the suit for a nappy change without fully undressing the baby. This keeps them warmer and helps them settle back to sleep faster.
Can I put a bodysuit under a zip suit?
Yes, and it's a great layering option for Australian winters. Pair a long-sleeve organic bodysuit underneath a zip suit to add warmth without bulk. Baby Goes Retro stocks a full range of organic bodysuit styles that layer easily under zip suits and snap suits alike.
