A baby’s growth in the first year of life is astonishingly rapid. While every child grows at their own pace, averages can be a helpful guide when choosing the right clothing size. In this article, we’ll discuss the growth curve, average sizes by age, and how Baby Season can help you always have the perfect size.

What is the Growth Curve?

The growth curve is a visual aid that shows how babies grow on average in terms of length and weight. Child health clinics use it to monitor a baby's development and to signal any abnormalities.

Important aspects of the growth curve are:

• Height: The average height of babies at different ages.
• Weight: How much babies weigh on average in relation to their height and age.
• Head circumference: Important for the development of the brain and skull.

For more information about growth curves, you can view the official WHO growth curves:

• Growth curve for girls (0-2 years)
• Growth curve for boys (0-2 years)

This growth data is also used to classify clothing sizes by age.

Average Baby Clothes Size by Age

Here is a chart of average clothing sizes by age. Every child is unique, so consider this a guideline:

• 0-1 month (size 50-56): For babies measuring 50-56 cm and 3-4 kg.
• 1-3 months (size 56-62): Babies grow quickly and need size 56 or 62 at this stage.
• 3-6 months (size 62-68): These sizes are ideal for a more stable growth period.
• 6-9 months (size 68-74): Suitable for babies who are starting to roll, sit and crawl.
• 9-12 months (size 74-80): For babies who are becoming more active and sometimes already taking their first steps.
• 12-18 months (size 80-86): During this stage, growth slows slightly, but babies continue to move around a lot.
• 18-24 months (size 86-92): For toddlers who are becoming more curious and active.

Tips for Choosing the Right Size

• It is better to choose something a little wider: Babies quickly grow out of clothes, especially in the first few months.
• Check regularly: After a growth spurt, a new size may be necessary.
• Use height and weight: These often give a better picture than age alone.
• Choose adjustable clothing: Rompers with snaps or stretch fabrics are easier to grow with.

How Baby Season Helps

At Baby Season we understand that babies grow quickly and it can be difficult to always have the right size at home. That's why we offer:

• Size updates per box: Easily adjust your baby's size with each new seasonal box.
• Seasonal clothing: Always appropriate and weather-appropriate.

TOG (“Thermal Overall Grade”) indicates how warm a garment, sleeping bag or blanket is. Here is an overview of TOG values ​​and corresponding room temperatures:

• 0.5 TOG: For temperatures above 24°C, ideal for warm summer nights.
• 1.0 TOG: For room temperatures between 20°C and 24°C.
• 2.5 TOG: For cooler rooms from 16°C to 20°C, perfect for spring and autumn.
• 3.5 TOG: For rooms below 16°C, ideal in winter.

Combining the right TOG rating with suitable layers will keep your baby safe and comfortable, no matter the season.

Spring and Fall: Layering for Changing Temperatures

Spring and fall temperatures can vary greatly. Layers offer flexibility, so you can quickly add or remove something. For example, choose:

• Long sleeve rompers
• Cotton pajamas
• Sleeping bags of 1.0 or 2.5 TOG for cooler nights

With layers you ensure that your baby is always warm enough without the risk of overheating.

Summer: Airy and Breathable Materials

During hot summer days, your baby needs light, breathable clothing. Choose materials like cotton or bamboo to let the skin breathe. For summer nights, these options are ideal:

• Light sleeping bags (0.5 TOG)
• Only a romper in very warm temperatures

Winter: Warm and Cozy

In the winter, warmer clothing is essential. Use materials such as wool or fleece to keep your baby comfortable. Recommendations for the colder months include:

• Pajamas with feet
• Sleeping bags with a higher TOG value (2.5 or 3.5)

At Baby Season, we understand the importance of providing high-quality seasonal clothing. Our baby clothing boxes contain essentials that perfectly match the temperature and needs of each season.

What is OEKO-TEX®?

OEKO-TEX® is a certification system that tests textiles for harmful chemicals. Products with this label meet strict standards and are guaranteed safe for human use. This is essential for baby clothes, as babies are more sensitive to irritants and allergens.
