So,the people you know wouldn't even call once a day to check up on a 5 month old baby?????
when my son was in day care I called once a day to check on him.
Some would on some days. Some would everyday.Some wouldn't on some days. Some wouldn't on every day.
I think it depends on alot of things and never once thought that not calling everyday or even mosts days meant a parent was not a good one. Surely not associated with murder. And calling every day was the same.
I don't think you can make blanket judgements about people based on one behavior. And I think accidents, mistakes, some egregious occur in both decent and hideous people.
