Bean sprout pillow sometimes end up on baby’s face

My baby is 2 months old and the bean sprout pillow somehow helps him sleep better, as he can feel the weight. We usually place on his tummy near chest, as im scared chest is too near to his face or he’ll have difficulty breathing. However, he’s getting more active and always moves his whole body, lift up his leg & butt etc, even when he’s sleeping and theres few times the pillow ends up either near his face or on his face and he would cry. So scary 😣 Any mummies experience same thing? How do i deal with this is i want to continue using the pillow? Or just place only half of the pillow on his body? Need advises pls dont bash me.
