Sleeping with bottle

My boy is 9 months old today and it feels like he is waking up through the night more and more! I'm not sure if I've encouraged the habit by giving him milk whenever he wakes up right from when he was born. Recently he's waking up every 2 hours and won't go to sleep without the bottle but he will only take up to 1oz before he's back to sleep again. I've tried soothing music, dummy and letting him cry for a short while but nothing else works. It's exhausting and my partner works away 70% of the time so Isn't there to take over! I've been told to try giving weetabix before bed has anybody tried this? Any advice welcome :-)
