Friend with hyperemesis

My friend is about 9 weeks pregnant and she’s so sick. She has a child from before and during that pregnancy she was just a little bit nauseous. Her husband isn’t doing much to help out and isn’t very understanding.

I’m trying to help out a bit with cleaning in the apartment and spending some time with the toddler, but I mostly feel useless and not helpful. It’s horrible to see her like this, she’s normally a vibrant, healthy woman that is active. But she’s a trooper and still trying her best to be a good mum despite being so ill. I’d like to help her more if possible. Also, are there any good forums about hyperemesis in particular?
