I think it is worth bearing in mind that picking puppies up, cuddling, and especially the act of enclosing them in arms is a very threatening gesture. You may not mean it in a threatening way (I'm sure you don't), but hugging/cuddling/holding are warm fuzzy gestures only to primates. It has the exact
opposite connotation to dogs.
That doesn't mean that, over time, dogs can't learn that that sort of behaviour from humans is NOT the threatening or overbearing gesture that they think it is, or that it *would* be if it came from a canine. But at the same time, it doesn't hurt to show a little sensitivity to your pup's perceptions and restrict your hugging/picking up actions to those she is comfortable with. Why is it different for you versus your husband or daughter? Impossible to know. Maybe you hug a bit tighter, or bend your upper body more completely over her, and hence appear more of a threat. Maybe its the opposite, and she's braver with you, hence more inclined to let you know that she's uncomfortable with it. The reason isn't that important really, but listening to her objections is

She's not a furry human, she's a dog - human gestures of affection just aren't perceived the same way by dogs, and it's only right that we recognise that and adapt to it.
My suggestion would thus be not to force it, but rather to restrict the picking up, etc to that which she is comfortable with. Over time, she will likely learn to be more comfortable with hugging-type gestures from humans.
