Baby knot is suitable for newborns.
Baby knot size is most suitable for about 0-2 year olds.
The nylon band is one size, or one size, and is suitable for a baby to an adult head. Only the bow part (baby knot) is smaller in this model than in a standard bow knot.
The collar is a really soft, "tights-like" material and stretches well and doesn't squeeze a child's head.
Please note that you will not leave the child unattended on the headband, and we recommend taking the headband off, for example when sleeping.
A bow strap is an accessory.
