If you had a premature baby or know someone who did, you may have heard terms like micro-preemie or teeny-preemie thrown around.

These weights refer to the size of your baby before birth. A micro-preemie is an infant whose weight is under 1 pound - 3 ounces, while a teeny-preemie weighs between 1 pound - 3 ounces and 2 pounds - 4 ounces at birth.

Baby Clothing Terms

When it comes to baby clothing, many different terms may be unfamiliar to you.

Micro Preemie: This refers to a baby born before 32 weeks gestation. A micro preemie's average weight at birth is between 1 and 2 pounds, 8 ounces. These tiny babies need extra special care and attention.

Teeny Tiny: This term refers to newborns weighing less than 5 pounds at birth. The average weight at birth for a teeny tiny baby is between 2 pounds and 4 pounds, 6 ounces. These little guys are also very fragile but have a better chance of survival than their micro counterparts.

Preemie: This term refers to any baby born before 37 weeks gestation (or 9 months). A preemie's average weight at birth is between 3 pounds, 4 ounces and 5 pounds, 9 ounces.

NICU-Friendly: A NICU-friendly garment is designed specifically for the Neonatal Intensive Care Unit (NICU). The clothing is usually made of soft fabric that will not irritate sensitive skin or cause chaffing when rubbed against tubes or wires attached to your baby's body during treatment in the NICU.

What's the difference between Teeny and Micro Preemies? Whose clothes should I look for?

Teeny Preemies are babies who weigh 3-4 pounds at birth. Their clothes will fit them until they reach 12lbs - 14lbs (5kg - 6kg). We recommend looking for a size 0-3 months (up to 12 lbs) or 4-6 months (up to 14 lbs).

Whether you’re a new parent, finding it hard to keep your baby’s clothes organized or a parent of several children finding yourself short of space, properly folding your baby’s clothes,

There are several factors to consider when buying preemie clothes:

The good season:

In some parts of the world, babies who have been born early may be able to wear an extra layer or two under their winter clothes.

In other areas, this could lead to overheating, which is not good for a premature baby's health.

So make sure you consider whether it will be warm enough for your little one during their first few months so they do not get too hot.

The right age:

Preemies tend not to grow very fast since all energy goes towards building strength rather than growing quickly, as normal children do.

However, there are exceptions.

These exceptions include premature twin boys whose growth rate resembles full-term twins.

Preemie Vs. Newborn Clothes

Preemie Vs. Newborn Clothes

When it comes to newborn clothes, there are several key differences between preemie and newborn clothing.

First, preemie clothing is smaller than newborn clothing.

It means that a piece of preemie clothing will fit a baby born at 37 weeks gestation (about five months and three weeks) more snugly than a newborn garment would.

It is because preemies often weigh less than full-term babies, and their parents may not be able to provide them with garments that are too large or bulky.

Second, preemie garments may be made from stretchy material.

They tend to be less stiff than their counterparts.

It means you can expect your little one to move more freely in the piece of clothing without feeling restricted or uncomfortable.

Third, some pieces of preemie clothing are designed with open spaces in the arms and legs.

Preemies can wear these clothes over medical tubing or other devices that help keep the baby warm during sleep, such as a blanket or shawl.

These garments are also easier to put on as they do not require buttons or snaps like those on other baby clothes.

At What Ages Do Premature Babies Wear Newborn Clothes?

Preemie clothes are designed to be worn until your baby reaches a specific weight.

The average size of a preemie is 6-8 pounds at birth and 20 inches long, but some may weigh as less as 5 pounds and be 15 inches long.

Some premature babies can be wearing NB clothes for several weeks longer than others, depending on their stage of development and health.

Ask your doctor if you have any questions or need help deciding what clothing to buy for your baby.

Preemies Need Extra Love,

You can not stick your baby in a pumpkin and assume it will grow into a human.

Premature babies need extra care, attention, and love.

In addition to all of that, keep them warm.

So if you are expecting a preemie, bring on heavy clothes.
