I hate it too, they are too thick and will never be crease-free and clean, especially with those non-behaved dogs. The germophobe in me cringes everytime when I see them rolling over the beddings or couches.
Regarding the pregnancy thing, I admit that I really thought she was, if I am being too curious, my bad. Like some of you said, she is an online personality, so she has to be aware of the fact that people will always speculate. Misscarriages are sad, but she doesn't bother changing her lifestyle habits (alcohol, coffeine, mostly vegan diet), does not bother with fixing any of her mistakes, but when someone mentions a baby, she is a victim all of a sudden. It is sad, but she has a healthy child, every other thing she wanted, yet is such a brat. When she became pregnant with River, she bragged about her carefree pregnancy, when the baby was born, she bragged of her being the best baby ever, so good, yet she could not wait to leave her to Mike and fly to States. She now got a taste of her own medicine, that's how many other women felt watching her being so ignorant about all of the good things in her life.
I am sure she will eventually have another child, I wish all the best for her, but I do feel there is something more to that story than we see. Even now, she doesn't seem too maternal to me and sometimes, she doesn't even seem too convincing about a topic of another baby.
