answer:  ok... I am going to do my best to help here.... and I think I will be answering all the questions but if not please post a followup or e-mail me directly at honoringwomen@gmail.com.

so... the first question... will they ever get it ? yes. they will. with alot of patience and loving guidance. I also had a preemie at 32 weeks. and it was quite something getting the nurses to let me nurse. I was just very hard headed and they were very un supportive... So... with what you have now to deal with... have faith. they will get it if given enough time to get it.

Preemies are a little different in nursing rules because they are just that... preemies. most often you have to start them out bottle feeding because their latch and suck reflex is so poor that they cannot effectively pull the milk out so supplementing is possible. the things you have going gist you are that there are 2, that they have had little exposure to the breast while in the nicu, and that mom is tired and worn down.

the good news, is that she has a supportive mother, 2 young babies that are term now, and although maybe a little delayed, are unbelievably resilient. There are mothers who adopt babies at 8 months old who have never nursed , and then go on to lactate the never before nursed baby. There is hope! I PROMISE!  the good news also is, that they are attempting! and any baby that attempts can become more successful over time...

another note... your daughter doesn't have to sterilize each bottle after every feed. that will save some time... its breastmilk which has antibodies in it to kill most germs anyway. general washing and rinsing is perfectly fine to do... hopefully that will save her a step.

preemies tend to get tired quicker when eating. this is SO normal. very frustrating and hard to get used to... but they do become stronger over time... it took my daughter about 3 months, and when she got it, she got it... and she went on to  nurse for 11 months.  it took alot of persistence but it worked.
because the girl was smaller, maybe shes also a little weaker... If she nurses when the milk lets down, you may try pumping to get the milk forward enough to let down , latching her on so she gets the instant gratification and then doing breast compressions ( squeezing the breasts while she is nursing to produce roe flow to make it easier for her while she nurses.  this is also only temporary. over time she will be strong enough to do it on her own...

I notice you said you have done everything you can think of. I don't know what all those things are so its hard for me to suggest what else to do... if you would like, you can e-mail me directly and I will give you my phone number so we can discuss it in person. The issues you have are multi faceted... and can be worked though but they are not as simple as writing a paragraph and fixing all issues... it often with preemies and twins , ongoing and alot of tweaking and reevaluating. I would love to help as much as I can. Please keep that in mind...

everything you mentioned is very normal nicu baby stuff...  If I could run every nicu, it would be done in a very different way.... but keep trusting you can get through this :)

NO, with perseverance, she will not have to always supplement with her own milk. She can go on to nurse both easily...if she sticks to it. and tell her, to pat herself on the back and know, that what she has done for her babies by pumping and giving that milk is far more than 90 percent of this country does. even with singletons.

the answer to the question of if its ok to just offer only the breast... I need more information before I can answer that effectively. and often, that done on a day to day basis and see what happens... I can also suggest getting a sns. ( supplemental nursing system ) it is a system that will help baby get more instant gratification when she nurses, by getting milk through a small tube while latched on. google it , get one and see how it works for her and the babies.  there should be a LC or LLL leader in the area who can help make sure it is working well. If I cannot help you enough through this , email or phone, I will refer you to a local resource to help you figure that part out too.

I would try hard to not worry about a schedule at this point. main focus should be getting them to nurse effectively. then setting the schedule in place will be alot easier...

I hope that helped! at least a little!
