OMG, that was like yesterday for me and boss. He cried, hollered, and whined all night the first 2 days to the point my fiance was gonna go get him and bring him upstairs, but it only lasted 2 days. On the 3rd day we told him to go in his house and he went and slept through the night and has been doin so for 5 months so far. Initially those first 2 nights were tuff and sleepless, but im telling you now, STAY STRONG!!!! It will be worth it in the end.
