Where and Why to Buy Premature Baby Clothes: Brands that Have Preemie Sizing

My oldest child (Margot, the “mar” in “Henmar”), was born at 34 weeks and 1 day. She weighed 5 lbs and 1 oz. Her birth was unexpected. She spent a month in the NICU (at two different hospitals). And I was kept at the hospital for 10 days after delivery.

In the hours leading up to her delivery (when I was being induced), I only vaguely shopped for premature clothes. I wasn’t sure what size of premature she’d be. So I bought nothing.

I discovered, shortly after, that there’s really only one standard or commercial size of premature clothing. Most preemie clothing fits babies who weigh around 4 to 6 and 1/2 pounds. Smaller babies or micro preemies are generally in the NICU for a prolonged period of time, wearing a preemie diaper, mittens, and a cap inside of an isolette. (There are so many tubes and IV lines that clothing can be an obstruction.)

Carter’s was the only preemie brand I knew of. And while Carter’s had some adorable staples, I was craving other options too.

It’s a blurry pic, but it’s us! My preemie and me, 2 days after she was born.

Do Premature Babies Wear Clothes?

Each preemie receives specialized care and whether or not they wear clothes depends on their medical situation. My own preemie (now 3 years old and strong as an ox) did not wear clothing for the first couple of days because she was closely monitored under heat lamps receiving 1:1 care. Afterwards, she was dressed in hospital provided preemie onesies and later preemie clothing that I brought from home.

It’s important I note that I’m not a medical professional: I’m just a mom who had a preemie and can draw on her experience in the NICU. (In two different NICU’s actually, since my daughter was transferred to a more specialized hospital.) I read some articles in The Bump, Healthline, and Very Well Family on the topic. Their words and advice echo my experience and what I saw in the NICUs.

Many neonatal medical professionals recommend avoiding clothes for preemies in the NICU because it may interfere with temperature regulation and with access to intravenous lines – but this may only be for the first couple days or weeks. It depends on how premature the baby is. But most preemies can and do start wearing soft, simple clothing towards the end of their stay in the NICU.

One NICU nurse explains they look for these guidelines before preemie babies can begin wearing clothes.

  1. Stable breathing and respiratory support.
  2. The baby has been weaned off their isolette.
  3. The baby weights at least 3 1/3 pounds (1,400 grams)
  4. The baby is gaining weight.

Other factors that determine preemie clothing readiness:

  1. The baby’s gestational age at birth (A baby born at 24 weeks will need more medical interventions over a longer period of time, and will not be able to wear clothing until they are closer to their gestational age of 40 weeks.)
  2. Skin maturity. Premature babies have very thin, nearly translucent skin and almost no body fat. It may take a few weeks, or more, for skin to develop enough to wear even the softest of preemie clothing. Premature babies lacking skin maturity will need isolette support, as its warm, humid environment mirrors the womb. Swaddling or clothing is avoided then because the humidity could cause the fabric to become wet and cold.
  3. Overall health of the baby. Every preemie is different, but most preemies are placed in a crib and (can) begin wearing clothing around 35 weeks of gestational age.

What Should a Premature Baby Wear?

Assuming that your preemie can safely wear clothes, it’s always best to consult with the nurses and medical staff. Even if you’re told “gowns” are okay, it’s best to ask about specific cuts, styles, and brands. You likely don’t want to buy premature clothing that you’ll need to cut holes through.

That said, here’s what NICU nurses recommend as the best clothes for premature babies.

  1. Simple cuts without fuss or frill. Premature babies are still meant to be inter-utero and they aren’t used to being touched. Putting on and taking off clothing can be stressful or overstimulating.
  2. Hats – covering the head helps a baby stay warm.
  3. Fun Diaper Covers – most of the time, even the smallest and frailest of NICU patients can wear a diaper cover. You can find fun prints and colors in even the tiniest sizes.
  4. Garments that don’t go over the baby’s head. Things that a baby can be easily placed in without having to go over their face like sleepers or kimono style (front-opening) onesies.

Why Should Preemie Babies Wear Clothing? What are the Benefits?

Outside of the isolette, preemies need to wear clothing for body temperature regulation just like children and adults.

As a mom of a preemie, I will say that seeing your little one in clothing helps you bond and relieves stress.

For the first several weeks after her birth, I felt like my baby was a Cyborg. She seemed part robot, part organic matter. There were tubes and wires everywhere. Every single time I held her, I would accidentally bump a wire or trigger an alarm.

  1. It’s easier to bond with your preemie when they look like a “real baby”. Until I brought in clothes for my preemie daughter, I felt like she was a pre-baby. Almost as if I was waiting on her to “turn into a real baby” so we could bring her home and dress her in all the beautiful clothing (NB and larger) I had readied for her. The psychological impact, of seeing her in cute clothes I picked out, was immense. Even if the clothes were picked out at the last minute in a sleep-deprived haze.
  2. It can relieve depression or the NICU blues. I felt more like a real mom seeing my babe wearing clothes – like she had been a term baby I could have brought home at birth. I was in the NICU for a little over a month, and it was heart-wrenching to see woman after woman arrive at the hospital and then get to go home with their baby only 2 days later. It felt unfair; we had been there so much longer. Those other moms were going home to spend their maternity leave at home. Meanwhile, I wasted weeks of my maternity leave in a dark, windowless enclave. With sticky, plastic furniture. Seeing my baby in clothing relieved a lot of depression and dark feelings. You need the little things to make you feel good.
  3. Visitors were less freaked out. It’s shocking for visitors to see a tiny baby with an IV line running through her scalp and feeding tubes and other wires poking and prodding her. A hat and clothing covered that up. And when visitors weren’t as freaked out (they did try to hide it), I was less stressed.
Only a few ounces bigger here than in the pic above, she looks much bigger and more “babylike” with clothing on.

What Size is Preemie Baby Clothes?

When talking about standard preemie baby clothes it’s size based. Standard preemie baby clothing will fit babies 4 – 6.5 pounds. Teeny preemie clothing is for babies 2-4 pounds, and micro preemie clothing will fit babies 1-3 pounds.

Always check the size charts when available, because sizing can vary by brand. At The Preemie Store, for example, their preemie clothing is for babies weighing 3-6 pounds.

For reference, newborn clothing usually fits babies around 5-8 pounds and up to 21.5 inches long, and 0-3 months can fit 8 – 12 pounds.
