everyone has given such great advise. congratulations on becoming an aunty!
do u know how long they are going to have that accom for?
maybe you can work around that, if they are right near the hosp then a better time to be there when you may be needed to do trips to and from when they are back home.
actually just doing something i found helpful, i had some ppl say to me if there is anything i can do, but i didnt like to ask, if someone just had of shown up with a few meals or to do some washing or something i would have thought that was fantastic.
emotionally they will probably be very up and down, so if they are cranky or say something you dont get or anything dont hang onto it, just let it go and know they are just very stressed with their situation.
