Woke up because the baby was crying and seemed hungry which is legitimate because he hasn't eaten anything since about 3 a.m., and at that time he only had a few sips. Well, when we woke up this morning the same thing happened again he only wanted to have a few sips and not drink a full meal. I honestly think he's getting bottle and nipple confusion and now he seems to prefer the bottle. I'm really stressing out about it because I don't know how to reverse it or maybe he's just not hungry? But he has to be because he hasn't eaten in a while.😟 This is really stressful. I never even wanted him to use a bottle in the first place, but the fact that he was in the NICU prompted that to happen. So, the next best thing that I could do was to pump for him while he was in there. And now, the doctor wants me to give him pumped breast milk anyways at least a few times a day so I can mix the rice cereal into the bottle to help his acid reflux. I also give him his vitamins in his bottle. So I don't really have much choice. I don't even have a regular hospital-grade breast pump anymore. I only have the hand pump that I got from the hospital, which is the Medela one and the little hand pump that I got from WIC. Those hurt bad. So, it's hard for me to continue pumping even when I need to. 😧😧
