What exactly did your ex do that would warrant a stay in a federal prison? Of course, I am speaking within the scope of the law and NOT your opinion.
Honestly, I know your mad but you sound kind of nuts. A good attny would probably say your ex does not have a parenting problem but more a problem shopping. Verifying the correct size of pullups then going from store to store to locate the correct size and grabbing the wrong length socks hardly equal prison time. Thinking that those two issues offer a window into your ex's parenting style does sort of make you sound unbalanced. Certainly in YOUR life you forget a size or grabbed the incorrect package when in a rush? Start thinking like opposing counsel (or get yourself a better attny 'cause it sounds like you need one) and stop getting so caught up in these stupid details.
