Hi C.!
I have a 15 month old daughter. We have started the binkie weaning process with her. She uses it when she is in the car and when she is going to sleep whether it be nap or bedtime. When she gets up in the morning we toss the binkie back into the crib and say "see you at nappy time" and when getting out of the car I say "Can I have the bink?" and she hands it right over. I think designating times that are appropriate for him to have it and be consistent with it only being those times is the best way to handle it. We will wean her off the car binkie next, some point before two!
Good Luck.
