It would be almost impossible to "Forget" an infant, if it was in the seat next to you.
If you are serious you are either not a parent or a very inept one and I do not apologize if this offends you. Let me tell you, if my wife or I EVER forgot a child we each would have known that the other spouse would have murdered us without any hesitation, and I do not mean in a kindly and simple manner such as using a gun. We would have painfully dismembered the other. 'Forgetting' a tiny infant is unbelievable and inexcusable!!!!
You would murder your wife if this happened with her and a baby?
ARe you for real?
I am a parent, and I don't think of myself as "inept", but I am also a Human being, with Human shortcomings, and distractions. I know I don't always perform perfectly under all circumstances, so I can understand how these tragedies can occur.
