LO is now 5 months old and was diagnosed with MSPI several months ago. I have been on a strict elimination diet since. Although breastfeeding until 1 year was my goal, I now feel like I have no choice. Although I'd still like to make it until then, I would like formula as a backup option for when I go back to work full time (I am working from home this summer), go to work conferences, need a night out, etc. LO just will not drink hypoallergenic formula. We've tried Elecare and Alimentum, and he won't have any of it. He was on Elecare for a whole week while I exclusively pumped (as per doctor's orders), and he lost weight because he wouldn't eat it. We try the Alimentum from time to time, and it's the same. He won't have any of it. Any tips?
