Sister in law had stillborn 😭

Im wondering if any1 here has any advice please? My sister in laws beautiful lil boy passed away at 31 weeks. Its been an awful few weeks for her and things were slow. Her lil boy was buried just this week and now i know its bound to have hit her harder than ever. Im just wondering what i can do 2 help from someone whos maybe experienced this, because i know nothing could possibly make this better but if thers anything, me and my husband would do it. We are also expecting our second baby in April, im 23 weeks and im sure thats bound to be so hard on her so im being super cautious in not hurting her feelings more.
