Is it normal for formula fed 1.5 months old baby to poop once every 3 to 4 days?

My LO which is only 1.5months old mostly poop once every 3 days. Usually during the 3rd day without pooping, she will be extra fussy, can't sleep very well, and kicks alot during feeding. Is this normal?

some of the experienced ones said is normal unless her stool is pale or white then u shud be concern. otherwise u can do the bicycle leg exercises and rub her tummy to pass out gas.
