Please excuse the intrusion. I've been reading along living vicariously through you in the hope that I can benefit from your experience and one day enjoy a bub of my own. :-) I had a friend of mine who had a bub with slow weight gain and breastfeeding challenges and she found some helpful info at this link. Not sure if it will be useful for any of you, but I wanted to post it in case it is.
All the very best to you and your precious bundles.
