Talk to your maternal health nurse about feeding at night, they don't really need it. You will find that once they realize it's not happening they will stop wanting it, seems harsh but you need to get rest also, you will find it's just a habit.

My oldest 3 have been shocking sleepers, it does get better eventually....Do you co-sleep? Maybe that would help??? Believe me it gets a better night s sleep for you and them and they get to an age where they want there own space. Our current co-sleep arrangement is a cot right next to our bed. Just a thought!!!!
