FTM question..!!!

Tatum • BOY MOM💙

So I’m a ftm and my son is a week and a few days old. His pediatrician put him on a different formula because the one he was on was hard on his stomach. I started the formula yesterday and every since my lo has been EXTREMELY fussy and hasn’t had a stinky diaper since. I’m freaking out and wondering what I should do or if this is normal??
