Babies are different and have different needs and preferences. Try out different shapes and sizes to find the perfect fit for your baby. It is our experience that the following sizes are the general and therefore also our common recommendation. However, all our sizes can be used from birth. It all comes down to your baby’s preference. It is not dangerous to give a newborn a size 3. However, because most newborns prefer a smaller size, we have made the following recommendations:
Size 1: 0+ months
Size 2: 6+ months
Size 3: 18+ months
Onesize: 0-3 years
