Baby doesn't want to get rid of pacifier.
He looks for it particularly at bedtime. He refuses to sleep without one, and even during the night, if the pacifier falls from his mouth, with eyes closed starts waving his hands around the crib looking for it, if found, he grasps it and put it back to his mouth, if he doesn't, eventually wakes up crying.
The only way of calming him when stressed or bored and starts yelling is via the pacifier.
What other alternatives can we give him?
