Talked to his neonatologist and he indicated, that without seeing him, he thinks that his issues in the past 2.5 months are "normal" at this phase due to the fact that he's no longer getting any immune system boost from my breastmilk. These issues started when I stopped pumping and we started taking him out.
If he's gaining any weight we won't worry and hopefully he'll grow out of it soon.
If he's losing weight or not gaining at all, we'll meet with him about how to imrpove the situation and see if something is contributing to his seemingly chronic congestion and severe gagging.
Thanks for your support!
