We have had more success today!
Firstly we found out that she hasn't been 'feeding' as it were, more just sucking. So she has lost more weight than they would like
It broke my heart when they told me yesterday. I feel like such a failure. Mw suggested expressing to top her up, but manual pump was shite to say the least. Had to send OH out to 24hr Tesco for some forumla as she just wouldn't settle. He also managed to get me a Medela Electric expresser, which is a God send! Still feeling quite tearful about it all, but today has been a bit better, she is actually satisfied after feeding and then is sleeping - whereas yesterday she was screaming all day.
Secondly we realised that one of the reasons she wakes up is she keeps rolling on her side. So we bought one of these:
Nature Sensations Sleep Positioner
So far, it seems to be working - albeit slowly. She actually slept for about 3 hours in there today! I managed to sleep at the same time, and feel so much better.
