I agree with the above - she may have mental health issues, but she's being treated, isn't she?
Another way to look at it - why do her mental health issues mean the child should spend more time with dad? What's the correlation? Does it reduce a risk of harm to the child? Wouldn't the risk be the same on any day the child is with mum? And if it was that bad, you'd be seeking residency, wouldn't you?
Like I said, if kiddo is fed, clothed and sheltered, mum is doing her job, so what difference does a diagnosis for depression make?
If you genuinely thought she was a risk, you wouldn't need someone to tell she's a risk.
If you decide to file an application in a case for further interim orders, I would seek the following:
1. Orders for increasing the child's time with the father to match the recommendations of the family report;
2. Orders to restrain either parent from bringing the child into contact with the paternal grandfather;
3. Orders for the father to complete a hair follicle test as requested by the mother, at the mother's expense; and
4. Orders for the parties to communicate via email and keep each other informed about the child's medical needs, including appointments, conditions and practitioner details.
