Wow thanks for all your respones.

Barb - Loren sleeps well through the day and is extremely unsettled over night. She has regained her birth weight. My night consists of feeding from 9pm on and off til midnight. She may sleep then till 2.30 and then up for another feed and then she is unsettled until some time the next morning (around 6am). I get up to her every 1/2 hour to hour. Most of that time she is grunting like she is trying to poo, but nothing comes out.

Loren is also chucking up after or even during her feeds. After every feed Loren cries and squeels with pain. I am lactose and gluten intolerant and my DD was lactose intolerant as a baby but she has come good now.
