Last three days We have changed formula milk from Nan pro to Nan excella pro...Also giving breastfeeding as well...In last 3days we could see she poop 6times per 12hours..She's 1.5months old..Last week she used to poop once per day...Is it normal sir as the frequency is increased in last three days.. Is there any problem in changing formula milk..?

A. Milk is very important for babies specially in the initial days of life breast milk is very important and should be given exclusively till 5-6 months of age . formula milk should be given only as a substitute to breast milk if due to any reason it is not sufficient to fulfill the demand of the baby. according to the age different stage of formula milk are there like stage 1 till 6 months of age stage 2 from 6 months to 12 months and thereafter stafge 3 . after one year cows milk should be started and any kind of hfdealth drink powder in milk should be used only after the completion of two years of age .
