Has anyone any experience of exclusively expressing? My lg is 7 weeks old and for the first 4 weeks we were getting literally no sleep. She was on and off breastfeeding from about 10pm til 6am then finally falling asleep for a few hours in the morning. After lots of reading and research I put it down to me having a low supply in the evening and/or her not taking enough during the day. For about 10 days I have been expressing for all her day feeds (so I know how much she's taking) and giving a bottle of formula in the evening before attempting to put her down to bed and then breastfeeding for nights feeds. After 2 days of this she has been only waking once between 12 and 7/8 for a feed and going back down reasonably well. I had the hv round on Wednesday and she scared me by saying my supply could dwindle if I continue expressing most of the time so I went back to breastfeeding for the last couple of days but she has been really restless during the nights since this. I fear it's because she just doesn't take enough during the day and I would like to go back to expressing so I know she's had enough but don't want my supply to dry up. Basically I just want to know if anyone else has successfully express fed for any length of time? Sorry for the long post!
