This is my son Zisan, he is very active and just recently started crawling. I make sure I am close to him all the time, but he fell from the bed two nights ago and I did not know as I was so tired my sleep was deep. I did not even hear him cry. My husband told me in the morning and I feel bad to not be there for him when he needed me. I feel guilty because if I was alert he may not have fallen. Fortunately, he didnt sustain Amy injury and he is doing fine. We have observed him for 24 hours and he doesn't seem to be in any kind of pain.
