topoftheworld, I read your message last night (I have not been on mumsnet for a few weeks) and it brought back all my memories of breastfeeding my ds. He was 8 weeks early and in ICU and SCBU for 10 weeks. Anyway after a sleepless night thinking of you I thought I should send a message.
I found it incredibly difficult to express. I started hand expressing drops into a syringe and then progressed onto hand expressing into a small bottle. After about 5 days I starting using the pump and found it very slow going. There was a room with electric pumps at the hospital and I would see other mothers get in 5 minutes what it would take me 20 minutes or moer to obtain.
The most important thing for me was to massage the breast and hand express for a few minutes before using the pump.
I also checked with the nurses each day how much milk my ds required at each feed. This slowly increased over the weeks and surprising so did my milk production. I used to express enough for each feed (and very occassionally a little surplus) so in my mind when I expressed at 3pm I pictured ds guzzling it down at 4pm! The little surplus I would put in the fridge and sometimes I had enough to freeze a backup bottle.
Somebody else mentioned expressing at night. I found this essential and could not maintain the quantity required unless I expressed at 2.30am and then again between 6 and 7am. This was when I produced the most. I also religiously expressed every 3-4 hours.
I continued to express for 3.5 months as ds needed some expressed milk to mix with his medicine. I breastfed him exclusively until he was 4 months old and he had his final breastfeed at 28 months!!!!
Having a premature baby in ICU is so stressful and it is not surprising that it is difficult to relax. There may good news one day and maybe
some not so good news the next; it is such an emotional roller-coaster for you, your family and friends. When ds was born, I was encouraged by stories from many, many people who had also experienced premature births and whose babys are now perfectly healthy children or adults.
If you do not already have one, I can recommend a comprehensive book 'Preemies - The Essential Guide To Premature Babies' by Dana Wechsler Linden, Emma Trenti Paroli & Mia Wechsler Doron. Perhaps you can order it via the internet. There is also a US website www.aapi-online.org which you may find helpful.
Finally, on the breastfeeding side La Leche League is fantastic. You can contact them via the GB website www.laleche.org.uk.
Good luck, I will be thinking of you and your dd.
