Gathering mom laughed because it is normal behaviour as far as she is concerned for the child so doesn't even think about it any more and is not really realizing how the child comes across to others. Any chance she was let go from her previous daycare for similar behaviours. Agree on the being stricter. This is the type of child that you can not give an inch with. At the same time you can only tolerate so much in the home before it takes away from the day for the others and time for the child to move on - possibly to a daycare centre where she can be assessed and have someone assigned to work on behaviours with her.
