Gift idea for the most amazing mother in law?

So I’m currently staying with my boyfriend and his mom. I’m pregnant and have had issues at home with my mom and dad being on drugs and my uncle sexually abusing me. So my boyfriends mom asked me to move in and she’s basically being a mother to me. She is so nice and sweet and just my favorite person in the world. She has such a good heart and I want to repay her. I already got her a shirt that says “blessed to be called Gigi” because she was wanting one really bad for when the baby gets here. But I want to get her something else too. Something that will really mean a lot to her. Any ideas? Can be expensive as I’m willing to spend as much as I can on her!
