The last obstacle to going home

Magnus is still doing great in every way except one: he's not gaining weight. This morning, his nurse practitioner told me that they want to see solid and consistent weight gain for two days before they let him go home. I was hoping that today would be day one of that, but given that he has puked up most of his last three bottles, it's not looking very likely. So frustrating! But of course, growing and gaining weight are important. We agreed to put him back on the fortified breast milk, but they're adding less of the fortifier than before (and the puking started before he went back on the fortified milk). At this point, I'll try anything to get him to gain weight!
