Velour or jersey baby sleepsuit: which to choose for the season?

Velour or jersey? Newborn or 1 month size? Front or back opening? Choosing a sleepsuit for your baby seems simple… until you go to buy one! So to help you get it right, I’m sharing the five criteria I always check before buying a sleepsuit. You’ll see: once you know them, everything becomes much easier.

Critère n°1 : la taille (et pas l’âge !)

C’est l’erreur la plus courante. Sur les étiquettes, les tailles sont indiquées en âge : naissance, 1 mois, 3 mois… Or, ces âges sont souvent trompeurs. En effet, beaucoup de bébés ne rentreront jamais dans la taille naissance. Et un bébé d’un mois peut très bien porter déjà du 3 mois.

In reality, what you need to look at is baby’s weight and height. Here are the guidelines to keep to hand:

Garment size	Baby’s weight	Baby’s height
Premature	up to 2.5 kg	45 cm
Newborn	2.5 to 3.3 kg	50 cm
1 month	3.3 to 4 kg	54 cm
3 months	4 to 6 kg	60 cm

For all other sizes, see our baby size guide.

Criterion no. 2: thickness, velour or jersey

It’s THE question of the season. And the answer simply depends on the temperature.

The velour sleepsuit is thicker and nice and warm. It’s therefore the ideal sleepsuit for autumn, winter and even early spring. It keeps baby warm all night long, under their sleeping bag.

The jersey sleepsuit is lighter and more breathable. It’s perfect for summer and hot weather, so baby doesn’t sweat at night.

One small caveat, though: at birth, even in the height of summer, choose a warm sleepsuit. In the first few days, baby can’t yet regulate their temperature properly. As neonatal paediatricians explain (Archives de pédiatrie journal, 2009), a newborn exchanges far more heat with their surroundings than an adult. So always pack at least one or two velour sleepsuits in your hospital bag.

So for the end of the year, don’t hesitate: go for velour. And remember to match the baby sleeping bag to the room temperature too, with our article Baby sleeping bag: which TOG to choose for the room temperature?.

Criterion no. 3: a front opening

It may not seem like much, but it makes all the difference! In the first months, avoid sleepsuits that open at the back. Instead, choose a sleepsuit that opens at the front, with poppers running all the way down both legs.

Why? Because at birth, you change baby between 7 and 10 times a day. With this type of opening, you can dress and change them without turning them over, so with less handling. The result: fewer tears for baby, and less stress for you. That’s why, for a baby, I always think practicality before style.

And honestly, I still don’t understand why sleepsuits for newborns that open at the back, or without poppers on one of the legs, are still being sold. For parents, it’s anything but practical: you wrestle with the sleepsuit at every nappy change, and it makes life so much harder!

Criterion no. 4: composition

A baby’s skin is very delicate. It’s therefore best to choose natural materials, and the ideal is organic cotton. Check the labels on the tag too:

• the Oeko-Tex label guarantees the absence of substances potentially harmful to baby’s skin;
• the GOTS certification guarantees the organic origin of the cotton: organic, ethical and healthy cotton.

Criterion no. 5: style

And finally, while you’re at it, you might as well choose a sleepsuit that looks lovely on your baby! A soft colour, matching the bodysuit or the sleeping bag… It’s the little pleasure that makes those first photos even more beautiful.

👉 It’s precisely to meet these five criteria that we created our sleepsuits. Our baby sleepsuit comes in velour or jersey, opens at the front with poppers all the way down both legs, and is made of GOTS-certified organic cotton fabric, Oeko-Tex certified. It is available in sizes 1, 3 and 6 months, in 15 colours. And you’ll even find the matching bodysuit!

Your questions about baby sleepsuits

How many sleepsuits do you need for the birth?

Plan on several sleepsuits per size, as baby often gets messy in the first weeks. Also pack one or two in your hospital bag.

Velour or jersey for the maternity ward?

In the first few days, baby needs to be dressed warmly. Velour is therefore a good choice, except in very hot weather.

Should you put a bodysuit under the sleepsuit?

Yes, generally: the bodysuit goes underneath and the sleepsuit on top. In very hot weather, however, a bodysuit on its own may be enough.
