A. first meet the dr for growth assessment. if growth and weight gain is adequate then no need to worry about milk intake. weight gain usually decrease with increasing age of the child. if urine output is more than 7 to 8 times per dady and child is playful overall then no need to worry much. see for oral thrush, ulcer , teething pain, discomfort,fever cold , colic which migdht be affecting the milk intake
