Hi, we're a bit different as my LO had always been waking every 2 hours but I was finding it exhausting and didn't feel certain he was getting enough so (when I finally found a bottle he would take) I started giving him some formula just before bed. He takes between 2 and 5oz, so not heaps, but it just helps to know he's definitely got food in his tummy when he goes down. It didn't happen straight away, but now (at 13weeks) he goes down about 6, sometimes wakes at 10 but otherwise sleeps on and wakes at 2/3 and 6 and gets up at 8.30. It also meant my boobs felt full for the next feed, and then after a little while I started expressing at the formula feed time which is helpful to have a time when I do this to stock pile milk in case I ever manage to feel okay leaving him for longer than a few hours!
