Feel overwhelmed with countless baby pajamas on the market? You’re not alone! Even at the same price, two products can be made from different materials and serve different purposes. So, which is the most important factor?
We’d say the best baby pajamas must hit a sweet spot—both stylish and practical for everyday use. Below is a checklist of crucial factors you need to consider to find the best fit for your baby.
Mastering Sizing and Fit – The Foundational Factor
Why Weight and Height Matter More Than Age

Every baby grows differently. Even if they are the same age, one can be bigger and taller than another. So, the recommended age (e.g., 3-6 months) is just for reference. Always rely on your baby’s weight and height and compare them with the brand’s size chart.
So, which is more important, weight or height? Some moms asked us. It’s a real dilemma when your baby’s weight matches the size chart but not the height, or vice versa. Our advice is to prioritize weight, with height being a close second.
The reason? Pajamas that are too tight can cause overheating, discomfort, breathing difficulty, and scratches (due to zippers).
Meanwhile, overly loose ones pose a risk of suffocation. For pajamas that are too long, you can always roll up the sleeves or pant legs. As long as it fits your baby’s torso snugly, you’re good to go.
Sizing Tip: When Should You Size Up?
If your little one is in the middle of two sizes, it’s a wise move to go for the bigger one for longer use. Babies grow so fast that they can outgrow a pair of pajamas more quickly than you can say “pajamas.”
That said, a snug fit pajama must be the top priority. If the bigger size seems loose, size down to ensure safety. But how do you know it snugly fits? The answer lies in this complete guide to baby pajama sizing and fit!

Two-Way Zippers vs Snaps: The Battle of Convenience

We’ve all fumbled with pajama snaps in the middle-of-the-night and worried about startling our baby awake. But you don’t have to. A two-way zipper is everything you need.
Sure, snaps reduce the risk of pinching your little one’s skin like zippers do. However, you have to unsnap the entire pajamas to change the diaper, which can leave your baby cold.
Some modern designs allow you to unsnap just the bottom for quick diaper changes. But it’s a real pain to line up and fasten all those tiny buttons, especially when you’re drowsy at night.
Two-way zippers, on the other hand, allow you to unzip the bottom of the pajamas smoothly in the blink of an eye. You don’t have to undress your baby’s upper body for diaper changes, keeping your baby warm. Zippers are also more secure than snaps, ensuring they won’t come loose under your little one’s kicking or tugging.
The Small Details That Make a Big Difference
Some little details can be more useful than you think:
- Fold-over mittens: Newborns have sharp fingernails, and they still have no control over their hand movement. So, it’s not surprising that they scratch themselves all the time. Fold-over cuffs come to the rescue by covering their tiny hands. They never fall off or get lost, and you can flip them over to have a regular sleeve. That’s why SwaddleAn includes this feature on our smaller pajama sizes (Preemie, Newborn, 0-3M).
- Non-slip grippers: Seeing your baby slip and fall is the last thing you want when they start walking. Non-slip grippers provide excellent grip even on smooth, slippery surfaces like wood and tile. You can find this amazing design in all of our one-pieced pajamas from 6 to 12 months.
- Tagless design: A small tag can rub against your baby’s skin, causing discomfort, itchiness, and irritation. But with a tagless design, you don’t have to worry about this.

Building a Pajama Wardrobe: Budget and Quantity

How Many Pajamas Does a Baby Really Need?
Most babies will need about 5-7 pajamas. This includes one to wear, one for laundry, and a few spares for accidents like spit-ups, or diaper blow-outs.
You’ll also want to have a couple of clean pajamas in the diaper bag whenever heading out. Not to mention, if you don’t have a dryer, it might take days for a pair of pajamas to air dry in winter.
Investing in Quality vs. Saving on Cost
Although high-quality pajamas like those from SwaddleAn can be a bit pricier, they're a bang for the buck in the long run. They are more durable and can withstand many washes, so you can save them for your next child.
Our pajamas are made from baby-safe, certified materials, delivering superior comfort that transcends time. Your baby’s sound sleep and your peace of mind start here.
