My 18 month old has taken to slamming head when she's mad or upset. She will on the floor, but will on her crib rail in the night time. It is so loud because of how hard she's hitting it that it sounds like construction.

Her forehead is COVERED in bruises. I cut up a fleece blanket and tied it around the crib rail for some padding. I can still hear the banging when she does it so I don't know that it's making a huge difference.

I don't know what else to do any experience?
