Do you use a humidifier for your newborn

Caroline • Caroline Renee Photography
I'm making an amazon purchase with my gift cards and I'm trying to prioritize since I can't afford everything. My coworker swears by the Vicks humidifier and I've been excited about it for months but now as I try to plan my purchase I'm finding I need to eliminate something. Do you use one? Wish you used one? Life saver? Barely used?
Side note: how many nursing bras should I have. I feel like I may go overboard
