Why aren't you sure it applies to her case? What had been said that makes you doubt it?
You have shown nothing to establish why their arrangement is harmful yet continue to push the point. That is not how you argue.
So in summary
Mum works early morning till afternoon then goes on kid duty in the evening etc
Dad looks after kid till 3pm then works late.
Gran takes kid from Fri afternoon 5pm ish till sun morning 9am ish. So 40hrs total with approx 20-22hrs night sleeping time in that. So 18-20 hrs ish wake time.
Family time on Sunday.
Kid doesn't attend formal CC and is looked after by nan 18-20 ish waking hours a week.
Both mum and dad work opp hours in the entertainment industry. I'm theorizing some weekend appearances as well. They need alone/couple time in there too.
I honestly cannot see this set up being so contentious.
In India and other parts of the world - some parents work very long days 6-7 days a week. Some families have one or both parents working overseas. So the kids are often farmed to grandparents to live with ALL year and parents only see their kids on annual leave.
These parents are still good parents. Their norm is just not your norm or my norm.
Sleep training is using a method to assist your baby to sleep longer and not to allow the baby to set the pace in terms of when it stretches out sleep, or sleeps through. So using techniques or methods to encourage more sleep which trains the baby to sleep longer. The controversy is that the baby doesn't get to that point in its own time.
Hopefully that hasn't offended anyone. Just my definition of sleep training.
