Yes, the only two options. You realise we are talking about grandparents? Grandparents have no innate legal guardianship over there grandchildren, it’s simply a social norm that they take care of them (often eagerly).
The second option isn’t even required of biological parents who are innate legal guardians let alone grandparents. I already said this once so the fact that you willfully ignored it is telling.
Also 18 years isn’t life, leave it to pro-abortion people to lie about the severity of everything simply to justify a personal convenience.
Nothing said here is true, and it’s so ironic that the Guardian makes a sob piece about this when what they did is illegal in most countries. (Including the UK where the Guardian is based).
