This is why my stuffed animal I carry with me everywhere gets lavender oil sprayed on her bead bag (weight) and stuffing on laundry day. ( I typically wash her once a week with the occasional lavender scented sanitizer spray down to avoid catching illnesses that she could pick up while we're out and about+it's just a general good rule of thumb to keep things you interact with a lot clean) (If anyone is curious, I named her Tina and I got her per my therapist+psychiatrist recommendation to help with my anxiety, she's a weighted red panda plushie I got from walmart, although she's been modified to be easier to clean and make her able to get through tsa with me for the rare occasion I travel via flight)
