Is it bad to top and tail kids in a king single?
Not at all in my opinion, my two would love to share and if DS would settle down and not act up would do it. The bottom half of her bottom bunk is just storage so would be a good use of space and I suspect we will end up doing it. We have normal bunk but I am not sure she will be ok to climb down in middle of night for a while as she is not very sure footed but could be trusted.
