Bean shaped things in babies stool

Lily • Happily in love & and a mother to a beautiful baby boy 👶| AP
These past 3 days, my son has been having small bean shaped things in his a lot. Theyre tan in colour...if i press them hard theyll kind of smush so i wouldnt classify them as hard but maybe rubbery. He is vegetarian however i havent given him beans this week...any moms relate?????
