Have you ever had problems with your little one wearing the seat belt? Every time my 4 year old (autistic) daughter gets in the car she freaks out when I'm putting the seat belt on, and starts a tantrum. I have to force her to stay still so I can put it on, but she manages to get her arms free and then I have to unbuckle her before she strangles herself. I put one of these car seat trays on as a seat belt. She gets distracted enough with the coloring book, so she's OK with it. But it's not eficient enough. I don't know if it's a normal 4 year old thing or if it's a sensory thing.
