Daycare sleeping arrangements

Nicole
Daycare puts son belly down on a boppy pillow in a pack and play with a blanket tucked around him. My concern is him suffocating on the pillow and not being able to turn. He can turn on and off his stomach and sleeps (turns himself) on his stomach at night. But the boppy and pillow would prevent him from turning. Idk how to have a conversation with them because im not good with confrontation but im scared as hell.
