Newborn (NB) & 0-3 Months
For newborns and infants aged 0-3 months, you'll want to look for clothing that is labeled "newborn" or "NB." These items will generally be smaller than other infant sizes, which is important since your baby will likely only be wearing them for a short period of time. Plus, most newborns spend a lot of time sleeping, so you'll want clothing that is comfortable and won't hinder their movement.
3-6 Months
Once your baby hits 3 or 4 months old, they will likely start fitting into clothing labeled "3-6 months." This size is usually a bit bigger than NB/0-3, with a few more inches in the waist and chest. Babies at this age are also starting to become more active, so clothing that allows them to move around easily is key.
6-9 Months
As your baby continues to grow, they will eventually need clothing labeled "6-9 months." This size is usually wider and longer than 3-6 month clothing, giving your baby room to move and play. You might also start noticing that your baby has a preferred Outfit—a certain style or type of clothing that they always seem to be drawn to wearing. If you notice this happening, don't hesitate to stock up on some of their preferred outfits in this size!
9-12 Months
The last size in most infant clothing lines is "9-12 months." This size is typically intended for babies who are close to a year old, and as such usually has a bit more length in the sleeves and legs than 6-9 month clothing. At this age, babies are becoming more independent and mobile—they might be crawling, pulling up on furniture, or even taking their first steps! So make sure you choose clothes that won't restrict their movement.
