You haven't indicated whether you and your wife are represented by attorneys in your pending divorce. Unless you and she can present an agreed modification of the temporary orders to the court, it is likely you will need an attorney to help you with this. If you are represented by an attorney you should be consulting with him/her about this. Ask your attorney about modifying the temporary orders in your case concerning overnight visits between the child and your wife. If you don't have an attorney I suggest you consult with a family law attorney who practices in your county right away about your options. You can probably find one who will consult with you once at little or no charge to you and you might wish to retain his/her services going forward.
