IMO it sounds like he isn't ready to be weaned off of it - and the weaning process is just causing more stress than peace, so why wean...
My DD uses a paci - and nurses to sleep. I love that if she is stirring a bit at night and has just recently nursed, the paci will satisfy her - and that it will satisfy her in the car or when we are almost done in the store etc. She only uses it at sleeping time, in the car, and on occasions when we are out and she is getting tired. Mostly it's just for sleeping - which she does almost every time we are in the car, so it's for the car too. She is 8 and 1/2 months. We don't give it to her at other times because I see no need for her - especially when she is a toddler - to be walking around with a binkie in her mouth all the time.
good luck with whatever you decide....
