If you’re preparing for a new baby, you’ve probably asked yourself at least once: “How many bodysuits does a newborn really need?” The answer depends on your baby’s age, how often you plan to do laundry, the season, and your lifestyle. But one thing is certain: bodysuits are the foundation of any newborn wardrobe.In this guide, we’ll help you figure out how many baby bodysuits to stock up on—by size, by day, and by purpose. Plus, we’ll explain why bamboo baby bodysuits from SwaddleAn are the perfect choice for newborns with sensitive skin.
Why Bodysuits Are a Newborn Essential
A baby bodysuit (also known as a onesie) is a one-piece garment that snaps at the crotch. It keeps your baby’s diaper in place, covers the belly, and provides a secure base layer day or night. They're easy to layer under sleep bags, sweaters, and pants—or wear alone during naps or tummy time.SwaddleAn’s bamboo newborn bodysuits are extra soft, breathable, and gentle on delicate skin—especially ideal for babies prone to rashes or eczema. Available in sizes from newborn to 24 months, they’re made with a premium blend of 95% bamboo rayon + 5% spandex, allowing for stretch and movement without losing shape.
Factors That Affect How Many Bodysuits You Need
There’s no one-size-fits-all number. Here’s what to consider:
1. How Often You Do Laundry
If you plan to do laundry every day, you may need fewer bodysuits. If laundry happens every 3–4 days, you’ll want more backup.
2. How Messy Your Baby Is
Babies spit up, drool, and have diaper leaks often. Some go through 3+ bodysuits a day.
3. Season & Climate
In warmer months, babies may wear short-sleeve or sleeveless bodysuits alone. In winter, you’ll need long-sleeve styles for layering.
4. Size Changes
Newborns grow fast. Having bodysuits in newborn, 0–3M, and 3–6M ensures you’re ready for growth spurts.
General Guide: How Many Baby Bodysuits to Buy

💡 Tip: Keep a few extra bodysuits in your diaper bag or car for emergencies.
