Help our twins' Mammy and Daddy stay with them

Hi folks, my name is Christina. My brother and sister-in-law just had twin boys, 15 weeks early. Parents are being discharged from hospital tomorrow but obviously they want to stay in Belfast so they are close to their babies. They live in Derry. I am doing this so that they can try and stay there with them. Anything is much appreciated. Thank u all so kindly
