My nephew was born today, please give me advice

Dear NICU Parents,

My sister had to be taken into the hospital today due to eclampsia. She lives in another country, so I do not have much information. She had surgery immediately and my little nephew was born. Sister was 30 weeks pregnant and the nephew weighs 600 grams. Does anyone have had a similar experience? I am also pregnant, two weeks behind my sister. I feel terrible, devastated. I really hope they are both going to be alright, but I feel like I should keep my distance for now because of me being pregnant, I think this is reasonable, but please correct me if you think otherwise, I don't want to cause her any further emotional pain. I want to send her something a bit later on when I know more. How could I support her the best way possible? What should I send her? Flowers perhaps? I don't know... Any advice ia appreciated. Thank you.
