The only problem I have with this book are those weird scenes in the barn where the kids have to milk the big cows tit. It's just weird to me. But what angered me more is where Kendra had to cut the cow's tit to retrieve some blood. I don't know why thay part was included because it seems like animal cruelty to me, but they don't make such a big deal out of it. And that could make children think that it is not a bad thing to harm an animal for some blood. Don't forget that children are very impressionable and ideas like these could lead to bad outcomes if they are not properly explained that this is not an okay behavior
