The neckline shouldn't be too big so that the head doesn't slip through again, but at the same time it shouldn't be too tight around your little darling's neck. If your child is lying in the sleeping bag and one of your fingers fits into the cutout, then that is the right cutout size. The same applies to the armholes: If the necklines are too wide, the heat loss is too great and the little arms may slip into the sleeping bag. However, the armholes should not be too tight and constrict. For this reason, our sleeping bags have adjustable straps so that they always fit perfectly. The sleeping bag should also be long and wide enough for your baby to have enough freedom of movement.
The temperature of the children's room is decisive for the right sleeping bag, 16 - 18° C is recommended. The TOG value tells you how warm the sleeping bag keeps your baby. The higher the value, the warmer the sleeping bag. All hessnatur baby sleeping bags have been tested by an independent testing laboratory. Decide individually which sleeping bag and which clothes your baby should wear.
One tip: You know your child best. Feel your child's neck: if it's damp, it's too warm in bed. Use the table below as a guide.
The right clothing in the sleeping bag depends above all on the room temperature - we recommend 16 - 18° C in the children's room - and on your child's individual sensitivity to warmth. The neck test already mentioned helps you to feel what is good for your child. The table above can serve as a guide as to which sleepwear fits your baby sleeping bag.
