These possessive views are creepy. It's not just your child. You share that child and, if both parents have PR, you are only able to say who can be around said child on your watch. You can't dictate who the other parent allows around the child unless there are legitimate safe-guarding concerns. Ultimately the main priority should be "is *child* safe and loved in that environment?". Pisses me off when one parent thinks they can dictate the parenting choices/style of the other parent. If you trusted them enough to have a baby with them, and (again) there are no legitimate safe-guarding issues, then get the do over it. If the other parent started trying to say "you can't have so-and-so around MY child" accusations of controlling abusive toxic behaviour would be flying.
