Just thought I would offer my PNS experience in response to Kathy Auerbach's post... I did not have a preterm baby ( 15 days late in fact) but had plenty of reasons for supply problems. Not to get into the gory details but my father died 6 hours before my baby was born... and my baby was born (late..) just 3 days after what should have been my last baby's second birthday (he died 8 hours after birth). So needless to say I was out of my mind with stress over whether this baby would be okay and grief over the loss of my father. My house was a menagerie of relatives as I was my dad's only in-town relative. It was, to say the least, tremendously difficult to establish a good nursing relationship. baby diagnosed with FTT at 2 week check... The Nurse Practitioner was sort of (in my opinion) sacrificing on the alter of ignorance as she gave me several cans of ABM and told me to supplement. No way I thought. Baby was 10#2 at birth and 9#15 at two weeks, appropriate void patterns... so pumping became critical as I was very adamant no ABM> I used a Lactina the first week as I was afraid of the PNS> When I got the PNS, though, there was no difference whatsoever. In fact, I kept increasing. I use one now (literally, I'm typing while attached!!) hee hee, and get great results... 20+ oz per day. So that's my experience. I'm not an LC so my experience may not apply to preemie moms...but I have nothing but raves about my PNS...from my freinds who use them, too. By the way, I wrote the ped office an eloquent letter about how she should have discussed pumping and alternative methods of feeding (not bottles) to me as I was so adamant that breastfeeding was how we would feed.
