I read online the best way to stimulate milk production is to double pump for about 10 to 15 minutes every 2 hours and also pump in the middle of the night once. Do you pump every 2 hours? I read at breast feeding forums that pumping for longer time, like 20 mins +, but doing it less during the day, like every 4 hours, gives less milk than pumping for less, like 10 to 15 mins, but doing it every 2 hours. If you are able to express a few drops then that is a good sign. I'd suggest just pumping for less more often if you are not doing it and least pump once in the middle of the night.
As for the blood check and medical history the response I got said:
QuoteA doctors' form will need to be signed from both your doctor and your babies doctor. We are able contact your MD if you would like.
After the packet and doctors forms are received. We will send you a lab requisition to get your blood tested. We pay for any blood tests needed, as well as the shipping fees to send your milk to us.
I'm unsure how the babies doctor part is going to work out. It could have been a generic copy paste since I did mention I am MTF Trans.They also send a questioner you have to fill out and return. There is also a 10 minute phone screening you have to do.
Is that comprehensive or should they ask for more?
And also:
QuoteWe require a 100 ounce minimum donation, and the milk can be up to 6 months old frozen at the time of donation.
Being able to lactate does not necessarily mean there is something wrong, but I can understand you. Reading online it seems that not a lot of women breastfeed for very long and that 'less and less' breastfeed. Unless it is a pituitary tumor

though I read those are mainly benign. I think I also read that pituitary tumors that cause a dramatic increase in prolactin can really increase breast size by a lot. I mean really big breasts.
