Like it's obvious she thought she could just get away with this shit because it was her FIRST reaction to the presence of the kid in the doorway.  Any sane human being would have gently pressed him forward or done ANYTHING else other than violently shove him into the doorway.    A special needs kid might be more difficult to deal with, but you are not the person for that job or ANY job that involves children if you are going to use physical force to get your way.
