Is this concerning to you?

A single parent mentioned one day during a school week that her and her child was going to the gym instead of going to school.
I feel like the parent might be viewing the child more as a friendship/buddy thing than a parent to a child.Why couldn't they go the gym afterschool?

I've even noticed unstructured patterns. The child missing school a lot either due to the parent oversleeping, parent being sick often or child constantly saying they are sick. So I am thinking the child is learning this behavior from the parent.

The child spends a lot of time on devices or playing stationary/subtle games and don't get out often. I've even noticed the child's social skills with other children isn't great that I believe he spends too much time with adults who are not that interested in his device activities than being outside playing with children his age.
