After the your baby has reached the nine month milestone there is generally no reason for them to be waking in the night for a feed. Or waking during the night for any reason for that matter! Lots of parents still report that their infants are not sleeping through the night at this stage however. 
Here are some common reasons:
- Sleep associations
- Illness
- Learned behavior
- Developmental milestone
- Wonder week
- Hunger (if the introduction of solid foods has been delayed or they are not taking 3 meals per day)
