My best friend offered to donate milk for me (I was inducing lactation), and I was totally thrilled! I think it would be wonderful of you to offer.
I would say just keep the commitment and the communication open-ended. It may be more of a commitment than you bargained for (the reality of caring for two children, nursing your own babe, and pumping). Just make sure you communicate with your friends what the expectations are and talk about it if any changes come up. Would you plan to donate long-term? Just for the first little while? I think whatever you wish to do is great, but just make sure they know.
