Keep the tiniest member of your family snug as they sleep with our newborn baby boy onesies. These are crafted to give your little one top-to-toe cosiness, with soft pure cotton fabrics (making them machine washable too). Simply slip one over baby's nappy and sleepsuit ready for bedtime and lay them down in the cot – there's no need for baby bedding, since these onesies are thick and warm.
We've got styles with long sleeves and toasty hoods which keep your child covered on the frostiest of nights. If you can really feel the chill, pick one of our 2.5 tog onesies, which have the same rating as some of our baby sleeping bags. Pieces with fluffy finishes on the outer and inner linings are perfect for wearing on rainy days at home, or for pulling on after bath time.
All of our boys onesie designs have popper fastenings up the front, so they're easy to remove in a flash. Even baby's tiny toes are taken care of thanks to enclosed feet. Look out for toddler-size options which come with slip-resistant soles, as well as newborn onesies for boys that include matching mitts.
While they might still be too young to dream of spaceships and dinosaurs, this doesn't mean we can't bring a little fun into their sleepwear. Choose from items with playful graphics embroidered across the front, or go classic with a spotted or striped onesie. Some even look like dress-up costumes – ideal for their first at-home photoshoot.
