Hello everyone, we'll be on IV for four months and we feed him every three hours, the day schedule was perfect. Now it seems like they swapped it out, he eats every 3.5-4 hours, the last feeding at 6 PM and that's it, then sleep and as if I tried to give him formula at 9 PM, he freaks out, throws up (he gains weight), cheerful, told the pediatrician not to make up stories and wake him up to feed him. Sleep from 6 PM to 9 AM. What is the feeding schedule of your mothers on IV, did you experience something similar in our age?
