Although I’ve seen the father of the child be comppassionate toward her, It has been told to me that his parents never showed compassion toward him as a child,- it is possible tht it stems from this,”
I actually misread this the same way as OOM did (no relation to Oomis). What does the lack of compassion shown by grandparents to their son, have anything to do with the son nonetheless being a compassionate father to his daughter? He is fortunate indeed to have developed empathy in SPITE of having a parent who was not a role model for the same for him.
It is VERY rare that a healthy, normal child does not smile. In fact, smiling is one of the first social development milestones. I would want to have this child evaluated. Does she act out, exhibit ANY type of emotion?
