Newborns need simple, functional clothing. They’re often fussy when they’re getting dressed and undressed, so outfits that go on easily are a must. They also need to be comfortable, so breathable materials like cotton are essential. Some babies may need additional layers for cold weather, so you’ll want to stock up on sweaters and cardigans in sizes appropriate to your baby.

You’ll also need plenty of onesies and t-shirts. These snap-crotch bodysuits are perfect base layers that you can pair with long-sleeve kimonos or wrap-style shirts. They’ll make changing a diaper easier, too, as you won’t have to unbutton or undress the entire outfit at once.

A hat or bonnet should be included in your newborn’s wardrobe to keep his head warm. It’s a great idea to look for one that covers his ears, too, as he might be sensitive to cold winds. A bib is also important, as it’ll catch spit-ups and spills.

To keep your baby’s legs warm, choose leggings and a few pairs of short- or long-sleeved rompers. They fit over a onesie and have snaps at the bottom, which make it easy to pull up or down as needed. You can also find footie pajamas, which are comfy for sleep or for wearing outside on a cooler day.

Consider adding a few pairs of socks to your baby’s closet, especially if you live in a colder climate. They’ll add a cute touch to his wardrobe and will help keep his feet toasty.

A few dresses or shirts with matching pants will round out his outfits. Dresses are a cute choice for newborn photos and special occasions, like meeting family members for the first time. You’ll also want to pick up a few pairs of shoes to help your baby get around.

It’s worth investing in some high-quality, organic natural baby clothes. This type of fabric is softer and more breathable than conventional cotton. Plus, it’s grown without any chemicals, which can lead to skin irritation in infants.

Another option to consider is a clothing rental service, such as Rent-a-Romper, which allows you to rent baby clothing and return it when your little one outgrows it. The cost of this service can be less than buying or renting brand-new clothing, so it can save you a lot of money in the long run. It’s a good idea to try out multiple brands of baby clothing when shopping, as sizing varies from brand to brand. You’ll know it’s time to size up when your baby’s clothes are tight or his feet or toes are straining the fabric. You can consult a sizing chart for specific clothing brands to determine the best size for your child.
