My 5 1/2 month old was a fantastic sleeper until one month ago when he cut his first tooth and suddenly quit sucking his thumb. Now he doesn't know how to soothe himself through the night and he's waking up wanting me to nurse him back to sleep every two hours. He thinks his pacifier is a toy and he is constantly pulling it out of his mouth to play with it or gum it. Of course, it upsets him when he pulls it out of his mouth because he can't figure out that he's the one taking it away or how to put it back in his mouth.
How do I get him to 1. start sucking his thumb again? OR 2. understand what his pacifier is and how to leave it alone or find it again when he pulls it out or spits it out?
