The best advice I can give you is to contact a board certified lactation consutlant (IBCLC) to make a home visit and assist you. You can find one here
www.iblce.org Just click on the "About IBLCE" button at the top of the page and the US and International registry pops up.
How old are your twins at this point? Are your the birth mother or were they adopted? How long have they been breastfeeding with the Lact-aid?
Best,
