I was pretty worried but Craig 'nailed it' on the first attempt. It's completely even; no wobble. I am very impressed! I wanted to keep the ladder, albeit also chopped, so that Seth could still climb into bed one day.
And the sensory den that was underneath? I moved that to the other side of the room.
With the curtains closed it's still pretty dark and the lights look just as cool. I actually think Seth prefers not to be so enclosed now.
