You should live in Colorado! I have personally witnessed and was involved in cases of mothers losing custody battles w/the fathers in court! If the mother is proved to be an 'unfit' parent the court will have NO leniency with that what so ever. You're wife is underminding the rules at your household and he is learning how to pit one parent against another,,not a good example to set for D2!
Believe me,,,BTDTGTT! (been there done that got the t-shirt)
And don't think for a minute that he can't figure out what he is doing,,kids can be very manipulative to get what they want or when they don't want to do something thats' expected or asked of them. If he is running to your wife crying chances are he already knows what he can get away with with each parent and he will use it to his advantage,,nip it in the bud now or it will spill over into other things(hmmm,,biting is normal, if going to PreK doesn't cure it via peer pressure, ask Dr. he maybe trying to act out his frustration w/this sitch & feels no control over certain things),,I would demand parenting classes along w/mediation. Some are based on your income, i.e. sliding scale, some classes are free thru human services.
Sounds like she is also trying to use him against you,,judges & mediators don't like that,,document everything(day, time, who said what, who did what, even better-copy e-mails & TM's) I know this sounds harsh now but you will thank God you have all of it later IF you need it. Who knows, once things calm down she may see the light w/the help of a teacher, other moms, Dr., etc.
Again, too bad you didn't live in CO,,parenting classes are mandatory during LS or D! One party consent recording is also LEGAL in our state,,it would be worth it to check out AZ laws. When she comes to pick up kids, you can secretly(make sure ok in AZ 1st)tape record the exchange BUT YOU have to be on your best behavior,,this will make you be at your best when you are speaking & meeting with her & if legal, she will have no choice but to listen to the court if she is confronted w/this evidence.
Good Luck, Kim
