What is the narrator saying in this paragraph?

Part five chapter 51

I want and explanation of this whole paragraph and I kind of understand this paragraph (Of course, Bonnie was pretty and a credit to her and Rhett adored the child, but she would not have another baby. Just how she would manage this she did not know, for she couldn’t handle Rhett as she had Frank. Rhett wasn’t afraid of her. It would probably be difficult with Rhett acting so foolishly about Bonnie and probably wanting a son next year, for all that he said he’d drown any boy she gave him. Well, she wouldn’t give him a boy or girl either. Three children were enough for any woman to have.)
