Gas issues

Nikki

My 17 day old baby just got switched to sensitive formula- and it’s helped with spit up and burping BUT he’s pooping much less and he seems to be having issues with farting now- he grunts until he turns red I. The face to try to get it out. He even does it while asleep(doesn’t wake him from sleep though) is this normal? I feel so bad for my little guy.
