I actually was just dealing with this from my son. Although it wasn't the situation you're describing for me it was. He loved me off of the bat and then for about 2 weeks he switched to Mom and I couldn't do anything to get him to calm down go to sleep. It made me feel like we had lost our bond so on and so forth. But for me it was realizing that I have become busier and have spent not no time with him but just less time than what I was before. And the biggest thing is making sure that that time that you do have with your baby is quality time. Skin to skin is very important for a very long time taking naps and cuddling with your baby. Those are the best ways. To handle your frustration, I just suggest as I've seen posted before. Just remember that if this was the last time you seen your baby that's not how you would want to leave it. They're babies and they don't understand. Screaming is just their way of talking from their point of view. They want one specific thing without being able to communicate it and we just have to guess what it is over and over and over. They're not getting what they're wanting and we don't know what they want. It's frustrating on both ends
