Ay, ang watery poop na pakonti-konti at frequently is actually pretty normal sa 4-month-olds, especially kung exclusively breastfed siya! A few of us moms noticed the same thing with our babies around that age, sometimes it's just their digestive system adjusting pa lang. But if may other signs like fever, bloating, or if baby seems uncomfortable or the diaper output is really excessive na, better check with your pediatrician just to be sure, kasi sometimes it can be a tummy thing na need attention. How's baby otherwise, playful pa rin, good latch pa rin?
