I would be be pretty horrified if my kid was watching movies that upset her during breakfast! I would be almost as upset though if the movies weren't upsetting them. I removed my kid at 4 months from a home based cater because the tv was on every time I was there - only as background but I don't think it is appropriate. There were other reasons but that was the main one.

Ds6 has had a bit of a problem with read alouds at school though this year. He edges closer and closer to the teacher until he is almost on his lap. The teacher thinks he is just engrossed (he is) but misses when it is more and makes him sit on his own mat for story time. I haven't done anything because I didn't find out until nearly the end of the year and none of the stories have been frightening enough to cause problems afterwards.
