A. Babies have natural rooting and sucking reflexes, which can cause them to put their thumbs or fingers into their mouths — sometimes even before birth. Because thumb sucking makes babies feel secure, some babies might eventually develop a habit of thumb sucking when they're in need of soothing or going to sleep.
