Good for you CiPA. Since you're going to be fighting for custody of your children: This would make a nice item when the matter comes up.
Chances are good that she's going to be painting a picture of you as a bad father. Document this incident because she is causing your son unnecessary stress by depriving him of his toys.
You don't need to tell her what you are doing. I would recommend that you start recording and documenting all conversations with her from now until the custody hearing. If you lawyer hasn't advised you on this, then get yourself an attorney who has a GOOD track record of getting custody for the father.
Other than that, chill out and enjoy the kids. Find that strong CiPA with the good PMA whose posts I was reading from last month. I'd like to see you back in that power zone.
