Other Sx ???
The breast fed baby can have a small smear of poo every feeding
or a giant crib filler poo every 7-10 days & be normal.
If all of babies stools have been soft to this point & baby is otherwise behaving normally, i wouldn't do much other than wait for the inevitable poo. I baby has dropped his/her feeding activity & changes play patterns, an exam may be indicated. Call the office & check with dr.
