Risks are always part of the equation when we strive for success. What risks were taken in the movie and why did you perceive these actions as risky? Pursuit of happiness.

Child bearer is another term for a mother. Like "birth giver" "mother" ect.

Yes, you can use it in a sentence.

"She is adopted but the kind woman in the red dress is the child bearer."

"Susan is a child bearer of the sweet little girl."

I have no idea if these are even good examples, but it is a strange phrase anyways, I hope I helped.
