5-month-old waking up for food twice a night?

My 5-month-old son wakes up twice a night for feedings, and I was wondering if there were any ways to reduce this. We don't mind feeding him overnight and we want to do everything for him, but we're wondering if there's a way to work it so he can sleep right through. He's eating rice cereal before bedtime, but gets bottles when he wakes up. Feeding him generally gets him right back to sleep, in fact he rarely opens his eyes through the entire process! So, it seems to just be that he wants food, not that he's sleepless or bored or anything like that. Any thoughts? Thanks in advance.
