It gets so much easier after they turn 1 so you don't have long to go.
What time does bubs go to bed and what time is his dinner and bath? I found that with my son he still woke once or twice a night until he was walking (then he was so tried from walking around all day that he slept through the night) He did have the dummy up until 9 months and that always soothed him back to sleep if he woke in the middle of the night.
Does he have a few naps during the day? How long does he nap for?
You can always try changing forumals to a thicker one? Or adding farex to his bottle before bed? Most babies will wake once or twice in the night, it's completely normal (not good for us tired Momma's) but he will sleep through eventually!
