I delivered twin boys at 36 weeks, and we were fortunate to not have a NICU stay. I wanted to exclusively breastfeed, but the boys were unable to effectively latch and suck from birth-I was told this was normal due to their small size and preemie status and have used formula. They were also tongue tied, we had this fixed about 1 week ago, but they still have difficulty latching at 1 month of age despite the nipple shield. Since then, I have been pumping with the hospital grade medela pump, taking the mother love supplement, had a home lactation consult and still only get at most 30 cc combined per pump session. I have to go back to work in about 1 month, so any help people can send my way to really ramp up my supply so I can achieve my EP goal would be great!
Re: breastfeeding help
I would look into domperidone as well, it saved me when I relactated with my first son. You can order it without a prescription from inhousepharmacy.biz, but it takes about 3 weeks to arrive.
In addition to the suggestions from PP, have you tried a supplemental nursing system (SNS)? It's the tube thing that you attach to your nipple, and the baby takes both your nipple and the end of the tube into their mouths. They get milk or formula from the tube while nursing, so it can encourage them to latch while giving your breast the stimulation it needs to produce milk.
The SNS helped me get DS1 to latch after about 3 months of not BFing at all, and he went on to BF until he was 16 months old and we found out we were having twins. If you can, get with an LC and they can show you how to use it.
Good luck!
