Baby Clothes Sizes – What You Should Consider

The Perfect Romper Size For Your Baby

Your baby’s onesie is too small again, even though it fit last week? Then I’ll show you now how to find out the perfect baby clothes size for your baby.

Maybe you already know this from your first child or are just becoming a mother or father for the first time, then you will quickly notice that an infant grows quite quickly in the first few months. Babies at that age get bigger and bigger month by month and after a few weeks the favorite romper is already too small again. A baby is usually 50 cm tall at the beginning and grows in the month around 10 cm.

To see what size your child really needs, we have a table here where you can easily see what size fits your baby best. This table shows all clothing sizes from premature to the second year of life.

This Is How The Cap Should Really Fit

The cute little cap that you see on just about every baby is more important than some might think. For babies in the first months it is especially important to wear a cap, because children lose most heat through the head. Whenever the baby is outdoors, the little head should be covered, because the infant must be protected from the sun’s rays and from cooling on cold days.

This Is What You Should Know And Consider About Baby Hats

Please note the material from which the cap is made, because baby caps can fit a little tighter or looser, depending on the fabric. It is important that the cap does not pinch. In summer, it is especially important that the cap is not too thick, because then it should only protect from the sun’s rays. It should not serve to warm, because the head should not overheat.

In winter, of course, the whole thing looks quite different. Since the cap should have a thick fabric to warm the head and protect it from the cold. It is best if the baby cap is also pulled over the ears, so that they are protected and your baby does not get earaches.
