Cutting out overnight bottles for 6 month old?

So I'm on day 2 of trying to cut out overnight bottles for my 6 month old son – he normally wakes up around 1:30-2am and I would give him a bottle and put him back in bed. Now I'm just trying to console him and get him calmed back down to go back to sleep without the bottle. The first night I watered down some formula, and he only drank about 2oz (normally about 6oz of non-diluted formula) and fell back asleep. Last night I didn’t offer any bottle, and he cried for about 30 minutes before he went back to sleep . He doesn’t take a pacifier (I’ve tried – doesn’t like them). Any advice or recommendations on what to do differently? I need some sleep!
