Ethan fell from the bed

Ethan fell from the bed 2 nites ago... :( After milk at 4:40am, he felt energetic and I let him crawl around and play with toys on my bed. I fell asleep and at 5:30am I was awakened by a loud noise. Ethan had fallen head down on to the hard floor. He cried for some time, it must be painful. Good thing there wasn't any abnormal symptoms. Eversince, we've moved to the 2nd bedroom, where I sleep on a mattress on the floor and next to the mattress is the bumper mat. A much safer environment I think.
