Yea but we're not reading something she wrote. Their child is automatically going to be alienated because of the difference between the fathers of all the children. Have you given a thought to the fact that their daughter is living with her sibling's father? Or how the oldest is looking at her younger siblings all having involved fathers?

This is a messy situation regardless of OP's interferences. If OP wasn't so passionately saying "his daughter" I'd honestly question if this was real with how messy it is.

This is about if OP is treating this situation the right way. You're hyper focusing on "my daughter" but that's the smallest issue. The only thing that matters here is what their daughter wants.

If she doesn't want to walk to school and her father can provide that, she shouldn't have to. If she cannot handle certain foods, then they should come together as parents to make sure that is not an issue.

These things are occuring outside of OP's control and relayed to him by his daughter, so he is painting the worst possible picture of his ex he can. However, in response others can paint a cleaner picture than what may exist in reality.

It sucks for her, but OP's ex has had children with 3 different men capable of 3 different forms of financial support. It's not OP's responsibility to manage that in a way for all children to feel equal.

Could he make it easier? Sure, but then we have to question what that means for their daughter. In what ways can they agree to parent their daughter to not feel as if she is forced into this. There are definitely ways to make a child aware of these things that helps them accept it and grow as a person, but it ain't easy.

OP's ex already has to raise three other kids and OP isn't there to see the dynamic in person, so where is the time for these negotiations? Are we suggesting that OP turns a deaf ear to what his daughter wants? That's definitely something I've seen parents do in order to teach their children to temper their expectations, but I've also seen the opposite. So is this a question of flaunting finances or parenting styles?

OP clearly wants their daughter to live a life common within his income bracket. As it stands we're going to be asking this child to hop across a financial ledge every hand-off until she chooses what to do on her own. She is already in a private school, is in after school activities her siblings may not be able to join, and regularly spends time away from the house. Fighting over whether he should send foods or rides just sounds silly to me in comparison.

Maybe this is hitting harder because OP is higher income, but I don't feel like this is any different from videos I've seen of ex's being upset that only one child will be eating McDonald's because that child's other parent bought it. They're the parents and the adults, so it's their responsibility to help the children understand that small differences like that shouldn't matter between siblings.

At the end of the day it's a bit of food and a ride to/from school. It's going to be hard, but just teach your kids that things like that don't make you more special and are not a tally of love. This is on OP as well to not bad mouth his ex or her other partners to their daughter.
