My 9 month old is breastfed. She nurses 4-6 times per day and eats solids twice a day. She has 5-7 wet diapers and poops once every day (usually). She didn’t poop yesterday, or at all today up until now (almost 9pm) and it was just one solid little nugget. She grunted for about 2 minutes and didn’t seem bothered by it. Her poop is usually a mushy texture. Is there a reason to be concerned?
