8 month old nodding head

Heather • 2 angel 👼🏽👼🏽 🌈 Mother to daughter born May 30 ❤️❤️

My daughter has recently started nodding her head up and down. She does it multiple times a day. Is it just a way of playing and exploring or it is something to be concerned about Neurologically? I am going to call her ped Monday morning.
