Just drawing on my own experience with our rabbit and how she behaved. We never lost any of the 5 babies they all grew up and were really healthy. Bugsly never stomped on any of them. She was a very good mother - even if you think she was a little "odd".Not only is that not normal, it's not recommended. A rabbit that will be in the nest box that often will ultimately stomp her kits. Their body structure does not necessitate drawing heat that way. As well as sleeping on top of fragile cargo like that. It has nothing to do with being handled...it's basic rabbit 101.
