I do follow some of the old people advice from back home.
(a) Make sure the sink is clean of dishes at nights before going to bed. I was told by my mother and my grandmother, that the Angels visit the homes at night .
(b) If coming home very late at night always enter the house backwards. My wife use to make me do that whenever we were coming home late at nights with my daughter when she was a baby.
(c) Put a scissors under the mattress of the crib. Suppose to keep the baby safe at nights. We did that too for my kids. My daughter does not believe it so she has not done that to her son
