Try feeding at 11, when a dreamfeed would usually be, then he should sleep longer. One night feed at this age is normal so feed him when he next wakes up. at his age anymore then 8 hours without food is a strech, your better feeding at 11 as I think he is actually hungry and thats why he wakes so often. Try to avoid the paci if you can, day and night, and see if this improves at all.
Don't leave him to CIO as it will only make things worse in the long run. If he cries go right to him.
