These are the No-Nos Abby wears to keep her fingers out of her mouth. We usually only have her wear them at night, but we occasionally put them on while she's awake...but not for the reason you might think! She has recently discovered that her filter (the thing on her trach that sticks out and acts like a nose, filtering and humidifying the air in her trach) comes off. She spends most of her day pulling it off and chucking it across the floor, or banging it on her high chair, or hiding it so we can't find it. The No-Nos come in handy once in a while!
