My two year old sees her father every morning for 2 hours before childcare, this week my ex has taken her to childcare sopping wet, he's not changing her nappies and he's not feeding her properly on weekend visits, last week she had only eaten chocolate and crisps when he bought her home at 2pm. When I went to collect her last week they were watching an explicit and violent television program, today someone tells me he has been spotted in town talking loudly to himself. I have a few reasons to believe his mental health may be suffering. I've confronted him kindly in an email about these issues and asked if I can provide nappies/food even though he pays bare minimum maintenance. Where can I find out whether this is grounds for withdrawing his weekend care? I don't want them to not see each other but I'd like it to be supervised.
