Depending on how quickly your baby grows, you’ll need a number of different outfits and sleepers throughout their first year. A general rule of thumb is to plan for two outfits and a sleeper per day, but it’s a good idea to adjust this number to fit your needs. Lastly, keep in mind that babies spit up and poop all the time, so you’ll want to have more items for spit-up or poop disposal than you think.

Onesies, bodysuits and rompers are the most popular types of infant clothing, but there are also singlets, creepers, blanket sleepers and even baby gowns available. These garments are made of a variety of materials, including bamboo and cotton.

Bamboo is a popular choice because it’s super soft, but it can be pilled easily with frequent wear. Brushed cotton, on the other hand, has a smooth, luxurious feel and is wrinkle-resistant.

Organic cotton is also a popular option for baby clothing. It’s also a more sustainable material for your child because it’s grown using natural and organic methods, and then woven in a plant-based dye process to ensure it’s safe for babies.

There’s a lot of variation in the sizing of baby clothes, so it’s important to refer to the brand’s size chart when shopping for your little one. Some brands will only show the higher end of their sizing range, so you’ll need to read carefully when choosing a new outfit for your baby.

When choosing a baby one-piece, look for something that’s easy to put on and takes up minimal space in the closet. Then, go for clothing with simple fastenings so it’s less likely to get lost or accidentally removed.

Newborn clothes tend to be a bit small, so you should consider purchasing a few extras to have on hand in case your baby hits an early growth spurt. This means clothes sized for newborns may be a bit too big for your baby, but you can always exchange them for a new set of 0-3 month sizes when they are ready.

Once your baby begins to walk, it’s a good idea to transition them from onesies and bodysuits to toddler playwear. This is because they will need to dress themselves for activities such as preschool and other outings.

You’ll need a few layers to cover up in during colder weather, so invest in some knitted and woven pieces for warmth. A couple of sets of socks and a pair of boots are essential for wintertime, along with breathable coats or vests.

A hooded baby jacket is an excellent addition to any toddler’s wardrobe because it’s a great way to stay warm in windy conditions and is a good insulator against the elements. This one from Gerber is a great value and is made from a blend of organic cotton and bamboo for a comfortable, natural fit.

The 0-3 month clothes are usually the most versatile, so you can use them for play and sleeping, and they’ll be a good transition into the toddler clothing. The 2T clothing is the next step up, so you’ll want to make sure you have plenty of options in this size.
