It seemed that Joe's family was very reasonable, until Kailyn violated Janet's rule of dating Jordan. Since then it's like they are the family of dysfuntion. They need to get some help and get back on the train of reason.
I will say that when it comes to having a say in what the other parent does when it's their custodial time, it works both ways. If you want, "right of first refusal," which means if the parent cannot care for the child directly, then they must offer the other parent the opportunity, instead of asking someone else to step in, then you have to do the same thing. You can't just leave your child with your mom or sister or some sitter for the evening, without offering the other parent the chance to come and get the child. Usually, it's better to allow the parent to use their time the way they want.
I understand what Kailyn was saying, but you have to think of it working both ways and most of the time, it can be quite inconvenient if you have to always offer the other parent the additional time.
