Is there any way I can stop him from doing this? He sleeps in boppy pillow because of his bad acid reflux. Doctors said was OK as long as strapped in. The blanket is under the pillow so he can't pull it up over his face. He gets up and bends in half to have his face on the blanket. He likes to pull stuffed animals to his face to "give them loving ". When I'm rocking him to sleep he grabs the blanket and pulls it up to his face to rub his face with it. It scares me because I don't know if he will do this and not turn his head to the side. Any suggestions please.
