I don't understand the comments about furniture? New babies don't need much, plus there will be another baby there as well so what's the issue? There are fantastic second hand cots, buggies etc., and your GD will just have to 'man up' and buy what she wants, your family should not expect you to be doing this. The proposal is very unfair, you will likely be cast as the villain here, but none of this is of your making. As others have said, your GD has her own room, they have a 5 bedroomed house and many families have to cope with less. Your DD is possibly panicking at the thought of two babies, a grandchild at the same time as a child, and probably can see herself raising two babies, not one as she planned. Help with baby sitting, provide a peaceful refuge for visits from those who need it, but don't be emotionally blackmailed by your family.
