Janeen,
Sorry that it tripled posted.
So you knew Hunter's mom? Was she a close friend? I am sure that with patience and perseverance and love, you will do great with BF. Was Hunter BF before his mom passed away? He will need all the love and comfort you can give him; BF sounds like a perfect fit for this little guy.
btw, 20 oz is fantastic. When I measured with my DD I never had that much. Pumping is way different than BF. Pumps pump you, babies milk you. The later is far more affective.
Maybe you should buy direct from the lact aid site. You can also find them on ebay on occasion. Have you contacted La leche league?
hoping/praying for you
Linda
