Fluffybunny, have you tried reaching out to the foster parents or whomever the guardian is? I want to encourage you to explore other options before bringing it to court, though I do realize that you are wanting to hurry. I would write a letter or an email or both to whoever is responsible for the kids and also ask the mother to plan another visit as soon as possible so you can tag along. And while you are there with her ask the people who have the kids if you can see them more so often or without the mother every time if she is not wanting to go so often, tell them your situation and ask them what would be workable. I hope it all goes smoothly and you are able to see the grands more often right away.
To go through chemo therapy or choose not to?
