how do you handle a bunch of kids on your own?

I want to help my friend. Maybe you can tell me something. I was listening to a Buddhist monk, and he said that one should try to help at least one person every day. So I've decided that person is my friend. She's a vulnerable, defenseless, creative person. When she got married, her husband seemed like a strong man. she wanted to lean on him, and be calmer, because she herself was very weak inside. At first everything seemed to be fine. She had the baby. And then her husband said that his ex-wife was not raising his three sons well, and since they have a family, these sons should live with them. It turns out that the friend has a newborn baby and 3 other boys, whom she does not know. And they know she's someone else's aunt. and she can't handle the kids at all. The husband does not help, as he thinks that the wife stays at home and "what else should she do". I can't visit her myself, she moved to another city. And how to help her remotely...
