Jamie Lynn explained in her book Things I have to say That her daughter, Maddie, had a life-threatening accident in 2017.
While at her grandparents’ house, Maddie went for a ride on her ATV or quad bike. Unfortunately, she apparently lost control and the ATV ended up submerged in a pond while tied up in it. Fortunately, the little girl survived and did not suffer much damage. But for a while, it didn’t seem like Maddie was going to make it, and Jamie Lynn felt her whole world stop.
