It’s not just up the hooter, they also shove things in their ears too. I remember sticking beads in my ears when I was around 3 years old. I wanted to wear earrings like my mum.
Luckily my mum put some oil into my ear to massage the ear and out popped the bead. Two minutes later, I did it again and I put it deeper into the ear, lol. She was not impressed with me obviously and she went to find where my beads came from and put them in the garbage to prevent me trying to do it again. It was a necklace that had broken and me being a rather active child, thought that I could put the beads in my ears.
