Gift ideas.. help!

My friends birthday is this weekend, she’s about 18 weeks pregnant. All of our friends got her maternity shirts for her birthday so I want to do something different. I’m thinking a pregnancy gift box. I don’t want it to be something she’d get at her shower. I’m thinking stuff she can pamper herself with throughout her pregnancy. They have one on amazon for $50 but I want to DIY it.. any suggestions on what to put in it?? What did you have or wish you had when you were pregnant to help you get through it??
