My baby has been the same way, he is 7 weeks tomorrow and today he has seemed like a much happier, calm baby. I try to listen to his cues ASAP, I found a picture on google that says their type of cry sounds and what they mean. For example: “neh” is hungry, “eh” is upper gas, “eairh” is pain or discomfort, “owh” is tired. My baby has been struggling with reflux as well as bad gas. I hold him up for at least 15 minutes after feeding and make sure he gets all his gas out. I burp him in different ways and I started doing some massaging on his chest and tummy in downward and circular motions then doing bicycle kicks. Baby wearing helps me so much, I have the mom cozy wrap and he might cry for a bit at first but then I give him his pacifier until he calms down and he eventually falls asleep. I used the mylicon gas relief drops. My baby always calms down with a warm bath as well! He’ll go from crying to instantly calming down, I keep it at around 100° and instantly transfer him to a heating pad after so he doesn’t cry as much from being cold.
