my 6 month old baby who was breastfed for the first 4 months and ate solid food at about 4-4.5 months and has currently been eating solid foods since. Then about 3 days ago started having yellow diarrhea that smelled of vinegar and has not hadd much urine in her diapers she is having the yellow vinegar diarrhea about 10 times a day for the past few days. She is acting like herself. Smiling. Giggiling. Just isn t sleeping as well. Seems to be somewhat dehydrated. But this is my first infant and I am going to call her doctor tomorrow just want to have some knowledge so I can help her and actually get some sleep.
