Unfortunately, grandparents do not have any rights to visitation in Florida courts. You would not have legal "standing" to seek visitation with your grand-daughter.
There is a strong movement by grandparents across the State to change the law. If this is something you felt strongly about, I would recommend discussing this with your legislature.
In the meantime, I am afraid your option for the next four years is to bit the bullet and play nice with your daughter.
When your granddaughter is 18, she will have the ability to make her own decisions.
Yes, you can seek visitation. Connecticut allows grandparents to seek visitation of their grandchildren. Here is a link to a Connecticut publication on grandparents rights:
The publication has a lot of helpful information. This is a process you can do on your own. However, family court can become a bit complicated, especially if your child and her husband fight you on the issue. You may want to consider consulting a family lawyer.
