Baby always loves his heated blanket mostly I intended that the room temperature will be 68F during the night (or even below). But, I wish, he will not use this thing as means of thumb sucking. I just couldn’t find ways of how he will find comfort in holding pieces of clothes and or blankets, then, suck his thumb. With that, he can sleep soundly. I am afraid though that he will ruin his teeth and gums if he will do it always. Hope he will let go of this bad habit.
