A. formula feed may lead to that if stool consistency is paste like or little watery nothing to worry about feed on demand, burp well , hold upright after feeds for atleast 10 to 15 minutes. if stools are excessivley watery or foul smelling better to consult with your doctor for examination and treatment, if bottle feeding maintain sterility as its a common source of infection
