What to do to help grieving mother?

A mom acquaintance (we have daughters both 8 and toddlers 6 months apart) just lost her toddler two nights ago. We are not supper close, but I’m devastated for her and want to do something.

I made her a vegan pasta dish (they are vegan) and donated to her go fund me but feel like I want to do more. I’m lost on what I can do.
