Girls, hello, it's been 1.5 months, the baby was on GIV because milk stopped, the pediatrician switched to IV completely, already for 4 days we eat only Nutrilal Premium Comfort formula. Problems with stool during GIV could go herself only on the 4th-5th day, once the stool was like Play-Doh and mushy yellow color. On IV stool is green-yellow, worries about tummy (colic, gas), can't go to the toilet by itself for a long time, helps with Microllax or candle, after going calm down. Who had such cases, what did they do? The doctor doesn't say much, says everything normalizes
