Hello moms! I need your advice. My 5 week old has not had a bowel movement in two days.. today being three. He’s a combo fed baby. I was doing mostly breast milk in the beginning but my milk supply has decreased a lot so I’ve been supplementing with formula. He was given enfamil at the hospital so I’ve been sticking to that until recently (3 days ago now) WIC only offers similac so I switched him to similac and has not pooped since. Im starting to worry. He still pee’s regularly, takes feedings well. I give him half breast milk half formula to slowly transition him to fully formula. Is this normal? Should I switch him back to enfamil? Wait it out? How many days should I wait? Please help
