Cori's ex is a freakshow like your ex too and we solved it by having his daughter have things that stay at our house and don't transport back and forth. She has clothes and toys and books and bikes and everything else at our house that we get her. If she wants to bring something to her mom's we let her mom know thst she would like one at her house. Anything nice that we have sent to her mom's house for her, her mom sells...
It is unfortunate but it is what it is
Aubrey is old enough now to even ask if she can just keep things at our house (her home she calls it even though custody has gotten switched around which we are currently dealing with again) because her mom will throw it away or sell it if she brings it there
