For much of my child's formative infant year, people were screaming bloody murder if we wanted our infant to develop a sense of facial expression in strangers and in public. They were also hell bent on banning much of the social events that people might bring infants to that may help develop early socialization. You do not get a more neuroplastic year than the first one.

There was a lot of stuff going on where one has to wonder how much we disproportionately sacrificed the children for disproportionately the elderly. It still deeply bothers me what effect this could have had on my child.
