@ Jo: MOST (85-90%) couples decide parenting plans themselves.
The ones that go to FAMILY COURT overwhelmingly have CONFLICT, DOMESTIC VIOLENCE, CHILD ABUSE.
This is patent rubbish but is boilerplate used by misandrist gender feminists and the acolytes working in the DV Industry. Most men have a metaphorical gun put to their head by lawyers saying agree to 14% visitation - its the "Gold Standard" - and cut your losses - the judge is going to give custody to the mom! Those that do go to court are usually brought by loving fathers who end up spending thousands of dollars because a non-co-operative and often vindictive ex doesn't want to share the children with one half of their genetic heritage.
The sites referred to cherry pick information and none of the information provided will withstand peer review. In a word they are biased.
Putting children in single mother households has led to a great deal of social problems in addition to it being more dangerous in terms of child killing and abuse. Check here. http://www.acf.hhs.gov/programs/cb/stats_research/index.htm
