Normally, I would disagree with him and argue the reasons as to why that would not be a good idea, but I was far too tired.
The night before I had been woken up at midnight to the sound of coughing. The little one had kicked of his blankets and had gotten chilled. I covered him back up and went back to bed. Half an hour later he had done the same thing again. He was so cold, that I picked him up and laid him in bed next to James to get warm. It wasn't long before the coughing stopped and soon the two guys were fast asleep. I looked at my phone, it was 2f. No wonder he was cold.
Realizing that I had lost my bed, I laid down in the little one's bed on the floor and attempted to go to sleep myself. It wasn't too bad as long as I stayed under the covers, however there were just not enough covers for my adult size body. While, most of me was covered, my feet ended up sticking out at the bottom and boy did they freeze even with my heavy winter man socks on. When I woke up the next morning, I was very tired.
When James got up, I climbed into bed with the little one and slept for another two or three hours. It took at least one of those to bring life back into my frozen feet. It was after this that James made the announcement.
So as evening came around that night, I prepared a bed for the little one in the corner of the top bunk. I laid his regular bedding down so that it was between the fridge, and two walls and then I laid the our big mink blanket down to make a fifth wall.
The little one watched as I set it all up.
"Mummy, why my bed up high?"
"Your going to sleep up high tonight."
"but Mummy, cats sleep up high. I sleep up high too?"
"Yes"
"I am a cat then. Meow meow."
I laughed. When I put him up there he was so excited. He loved being able to look down. That night he slept so peacefully. The warm air from the heater drifted up to the top so he had no need to keep his blankets on. He didn't even come close to the edge which was good. He woke up before us, so he called me to come getting down. I woke up and got him down.
Last night was the second night he slept up there. Still no problems. This time we were up before he was, so we moved him down to the bottom bunk before we started moving. He slept for another half hour before he woke up ready to go for the day.
So it seems that putting him on the top bunk has worked out so far.
