It sounds like some family therapy may help. A safe space where you can all express your thoughts and feelings and try to find a practical resolution. If both the new parents are working could you all help them find a flat and organise a proper childcare rota. They probably need to live independantly to allow them to take responsibility for their own lives. Good luck I completely understand your feelings and I think they should be respected,
Words you don’t often see now.
Why do people lie online are they living a fantasy or winding us up?
