Do you consider this behavior insensitive?

Here is the scenario: A young mother suffered a miscarriage within the last two weeks. Two people are having a conversation about taking care of a two year-old and a newborn while the mother who had the miscarriage is in the other room. The father is in the room with the two women having the conversation but is engrossed in another conversation. The woman who lost the baby enters the room at tail end of the conversation and at hearing the word “newborn” leaves the room.

At this point the father loses his mind at the women who were discussing having two young children. He minces no words letting them know they were super insensitive to have a conversation such as that with a woman who recently lost a baby in the same house. It escalated to the point that the father starting yelling at the women and stormed out of the house.

So my question is, was the conversation inappropriate or was the father out of line making such a scene?
