I'm giving 3% fat contains aavin blue pasteurized milk (nice) around 2 times and nan pro formula stage 2 around 4 to 5 times per day. but I felt aavin blue gets easily digested as if she drank water. so can I switch to green colour aavin pasteurized milk where the fat is 4.5% . my baby's weight is 6.13 , she had completed her 6 months and this is her 7th month.
