Baby bodysuits are the workhorse of a little boy's wardrobe, the layer that goes under everything and stands alone on warm days. This collection gathers bodysuits for babies roughly 3 to 24 months, in styles that make quick changes and endless snuggles easier. If you're building out a first wardrobe or just replacing the ones that always seem to disappear in the laundry, this is a practical place to start. For more everyday essentials across the age range, browse the wider baby collection.
To pick the right size, go by your baby's current weight and height rather than age alone, since babies grow at their own pace. Our sizes by age guide and the size converter can help you match measurements to a size. If you're torn between snap and zip closures, our zipper vs snap guide weighs the trade-offs.
- Buy a mix of short and long sleeves to cover changing weather.
- Check that the neck opening stretches enough for easy over-the-head dressing.
- Keep a few spares on hand, since bodysuits get changed often.
