Does this sound normal?

My 6 1/2 week old baby doesn’t have much time where he is settled/ calm. He’s been this way ever since he was born. He is either eating, sleeping, or crying. He’s gaining weight well and on Pepcid for silent reflux. He naps and sleeps well, but when he wakes up we change him and he cries until the breast. He feeds for 45 min - hour and either falls asleep or starts crying. He doesn’t ever just “chill.” I can’t put him on his play mat or bouncer or anything without him crying. In your arms he will cry unless you are actively soothing him. He will calm in a carrier, stroller, or car seat and falls asleep. I’m just worried that he will fall behind if he’s not getting much play time in. Does this sound like just a baby thing? I get sad when I see other babies able to hang out on a mat or even in your arms and just chill. FTM here and overthinking everything!
