He fell off the bed for the first time today ? He hit his head on the wall. The baby was left near the fireplace. He shouldn't have fallen. It was in the room of my husband but we had another child visiting. My husband just turned away from the other child and our little one somehow tumbled and fell. He cried a lot, he was scared, and I started crying too. Now I worry. But there is no vomiting, now he seems calm, but I am very worried. Who has experienced something like this? What did they do? Was everything okay?
