Seatbelt restraints?

Kayla • 12/30/16❤️ 1/20/18 💑 12/12/19💙

Can anyone recommend anything, our 2.5 year old can reach the back seat seatbelts sitting in her car seat rear facing and this kid wraps it around her arms, legs, neck. Basically anything she can. Trying to find out if anyone knows of anything that can help to keep her from reaching the seatbelt or keep it locked back in place?
