Exclusive pumping. 5 month old baby. Doctor suspects milk protein intolerance because he had 6-8 loose stools. Now I've been on dairy free diet for last 4 weeks and loose stools are down to 2-3 a day. He's drinking more than I'm pumping, so I need to supplement. Tried nutrimagen and alimentum. Baby HATED both. Tried ready to feed Alimentum, had it for 1-2 feeding but then rejected completely. Thinking of moving down to Similac sensitive...Freaking out as my freezer stash is running out. Please help!!!
