So my little bean is 8 weeks today and has been sick with a cold/sinus infection since Thanksgiving. He had been starting to drink more and sleep longer right before he caught his cold. He inverts the nipples on medela slow flow and only drinks 2-3 ounces at a sitting (eats every 1.5-2 hours). Should we try medium flow to see if we can get more food in him? He still seem hungry a lot of the time but falls asleep quickly once he hits 2 ounces, sometimes a little less. He's only 10 pounds 14 ounces and his growth curve slowed down when he started getting sick. He started his antibiotics last night so we are hoping eating and sleeping more are in our future. What do you think about switching to medium flow?
