Mardoin, I agree, your pup is safe and should learn to feel safe, in a crate at night.
Mine took about 3 nights to learn that his crate was his bedtime place, and that I'd take care of him and come back for him when the alarm went off (or he cried to go outside, within reason). He can see me, has a blanket, and does very well sleeping from 10:30 pm to 5am in there. I can rest too, knowing he is safe. I got Barney at 8.5 weeks, and he only ever had about 3 accidents in the first few weeks - otherwise is fine and dry in the morning. He slides out for a hug, and we go outside right away. Everyone is happy and safe
