Princess has slept in my bed since day two, I wasn't strong enough to crate train her.

I kept the door shut & made sure the whole room was safe for her.
Once she got out of her naughty puppy chewing I'd leave my door cracked so she can sleep else where in the beginning of the night. The house is still super puppy proofed so I don't worry too much about her getting into trouble. She always joins me at wee hours of the night though. It always makes me smile when I'm half asleep & feel her come plop down next to me, as she
has to be touching me.
