Difference between size 3m and 0-3m? (2024)

FAQs

Is size 3M the same as 0 3M? ›

As you've seen, 0-3 isn't the same as newborn and if it lists just one number like 3m that is the max. Keep in mind though these aren't strict timelines. Most clothes will have a weight and length max listed which is more accurate than age since babies come in so many different shapes and sizes.

The most important thing to note with respect to sizes is that they represent an average range, and the size listed will be the upper limit of that range. So, if you have a 3-month-old, they will likely be ready to graduate from 0-3 month sizes into 3-6 month sizes if they haven't already.

For example, size 3 months often means that it fits babies up to 3 months of age. Many 6-month-old babies wear 9- or 12-month clothing.

You may also notice that Carter's baby clothes are labeled with a single size instead of a size range (for example, 3M instead of 0-3M). Carter's clothing that is labeled 3M typically compares to the 0-3M range in other brands.

If you're buying for your unborn baby, in general it's best to buy 0-3 month clothes, as newborn size can be outgrown very quickly. It's important to never dress them in clothes that are much too big though, especially sleepwear. It could be a suffocation risk.

The longest a baby usually wears newborn is about 1-2 weeks after their due date (even if born early- by the due date they are usually in newborn size). Therefore, for a new baby gift, I would go with a 3M (0-3M) or 6M (3-6M) size to get a little longer wear.

‍Absolutely, if that's what works best for your family. Just know that the 0-3 months size will probably be a little on the large size immediately, with the child growing into the size over the course of the next month to 6 weeks.

The 3-6 months tend to be sized to fit up to 6 months, and the 3 months ones are sized roughly for 2-4 months.

There is no set definition for the newborn age range; however, some experts consider an infant to be a newborn up to 28 days, whereas others suggest it's up to 3 months of age.

0-3 Months Clothing Size

Some babies start wearing this size when they're not even a month old. Since your baby will be growing pretty quickly at this stage, it's a good idea not to go overboard. Stick to the two outfits a day rule, making sure you have at least 14 different options to experiment with.

By 3 months, your baby will have formed a strong attachment to you. They will respond to you with lots of smiles and might even talk back to you in their own way. The worst of the crying should be nearly over, and you can really enjoy your baby as they grow into their own little person.
