Yes, it's common for babies to shake their heads back and forth, especially when they are excited or trying to soothe themselves. As long as your baby is not showing any signs of discomfort or pain, it's nothing to worry about. Enjoy watching your little one grow and explore the world around them!

My one twin was doing it last month. It was super cute to be honest but now has stopped. Completely normal though :)

Yes my little one does it when he’s excited or playing/copying his sister 🥰

Yes definitely!!! She does this to self soothe or if she gets excited

Yes!! Every now and then she will turn her head from side to side really quickly. From what I’ve been told it’s just them exploring their body, self regulating and playing around. I was told that if it persists for a long period of time to discourage it and ask a medical professional if it’s concerning you
