This might sound a bit callous (and I know it's more left field than callous but it's my only entry point to this topic) but your story kind of reminded me of a time I visited friends for a weekend at college. A friend of theirs had a new born litter of 1/2 Black Lab 1/2 Pit Bull puppies (the cutest, jet black pups) and my buddy and his girlfriend adopted one, Kujo. Their goal was to get their new puppy used to being and sleeping alone by making sure it slept outside of their bedroom every night. This was the second weekend they had the dog and I, of course, was outside of their bedroom on the floor. The cold carpet. The living room was the only other room besides the bathroom, which we all wanted to keep dog free for everyone's convenience, in their small college apartment. I was told to try not sleep / cuddle with the dog overnight, but not sternly. I'm a light sleeper as it is and after about 15 minutes of listening to the little guy cry and whimper I caved in figuring one night of sleeping cuddled up with me couldn't ruin a K-9's entire life of attachment. Plus I was on the floor and as you can tell I'm soft as it comes with animals and children. I'll never know whether my softness that night ruined Kujo's sense of attachment but I will tell you right now, as someone who has always wanted kids I can't imagine I'll be able to keep my own flesh and blood at a distance while they are crying and calling out all night long :*(. I have so much respect and am in awe of parents of all types. Keep kicking butt!
