i'll be the odd-ball here and say that yes, you can probably begin nightweaning. Doesn't mean he'll suddenly go the entire 10 hours without eating but it sounds like he's old enough (and presumably big enough weight-wise) to go a longer stretch at night.
That being said there are several approaches to night-weaning.
1- replace one of those wakings with a small bottle of water (couple of ounces). Have dad give it to him. After a few nights of not getting to nurse he'll stop waking at that time. (he could move the waking time to be earlier or later and you'll have to decide how you want to handle that).
2- offer a pacifier
3- choose a timeframe that you don't want to nurse (ie midnight to 6am). nurse him/dreamfeed just before that time begins, then if he wakes anytime during the "milk went night night" time, don't allow him access. (For us that meant DH took him and I slept with a shirt and bra on, DS did NOT sleep next to me during that time).
4- you can also time how long he nurses and reduce it by one minute every 3 nights until he stops waking up.
5- increase his intake during the day (offer larger bottles, offer breast more often).
We nightweaned DS at 11 months but in hindsight I wish I'd done it MUCH earlier. He was up every 2 hours until that time. 3 rough (but not horrid) nights and then we all slept MUCH better. Our approach was to pick a timeframe, boobs were not accessible during that time (if DS was in our bed he slept next to DH, not me), if he woke up DH offered him water and repeated "the milk went night night, it's time to sleep now, night night" over and over. If he got really upset (which I think happened a couple times) I'd go get him and try to calm him down without nursing (but I usually gave in and nursed him). We expected 5-6 rough nights, the first night was rough, the 2nd less so, the 3rd even less and then no more.
good luck!
