I must say, you're awfully hostile.
I've heard that parenting plans can include things like discussing with the other parent when its okay to introduce a new partner to your kid. Of course you both have to agree to it.
1. You sound more like a hostile 20 some year old. Not being mean but stating my opinion.
2.Nope I've never heard of any parenting plan that says each parent must talk to and agree with the other parent about who what when why and where they date or friends or family, EXCEPT, as you have already been told, the person is deemed to be a danger to the child.
Now think about this in a LOGICAL manner**************Did Mom or Dad have to discuss with anyone if they dated, slept with or had a child with each other? Nope! Why? because.....oh oh here it is...they are A D U L T S, that's why. If mom was so concerned with it, she should have stayed with him, then the issue would be moot.
I don't like that my kid has gone through 8+ women that I've known of and met, but honestly, that's his Dad's game when our child is old enough to realize it and ask questions, not my problem and I have all intentions that if our child asks me, I will say, "not my business baby ask your Dad".
Your daughter needs to let go of the "golden uterus" syndrom and deal with it
