Cody fell off from his bed

I went home yesterday after work. My father in law told me that Cody fell down. And now he was sleeping. I went to my bedroom & saw Cody forehead was blue black bruise & swollen :(

Mother in law was preparing dinner. Father in law was accompanying Cody on the bed. Father in law went to pick up call & don't know how he fell off from the bed. I never asked them much.

It's not easy to look after a kid & my parent in law are old already.

As long as Cody is fine, and he is able to eat, drink & play. I'm happy leh :)
