I am assuming the mother of the child is an adult.
If so, she has every right to do whatever she wants with the baby (provided its within the law) as well as whom she allows to be near the baby.
It really doesn't matter how much money you spent on any of them. No one made you do that so there isn't much you can do there. I would think it was done FOR the baby.
Unfortunately, you don't get to use any of that as reasons why you would have rights or a say in anything.
The mother of the child chose this father.
Whether the father is a good person, man, father or etc has no bearing on the fact that it IS this child's father and the mother chose to keep him involved/in the picture.
I am sorry you are in this situation but IMHO the best thing you can probably do is to allow your daughter to suffer the consequences of her choices.
Be there for your grand child and your daughter if she wants you in her life, but allow her to do whatever she feels is best for herself and the baby even if you don't agree.
If you raised her, you have to trust that you gave her the tools to do the best she can.
