For safe baby sleep, we recommend a sleeping bag in the correct size: the child's body length from head to toe plus 10 cm. In this table, you'll find our size recommendations:
without feet
with feet
If your child is between two sleeping bag sizes, for example, if it still barely fits into the 70 cm sleeping bag. We recommend purchasing the larger sleeping bag size (in this case, 90 cm) and sewing the oversized armhole slightly smaller with a few stitches. The sleeping bag should not slip over the baby's head. This tip has two more advantages: your child will feel comfortable with the freedom to move and can wear the sleeping bag for a longer time.
