Switching formula

Christina

My son is 5 months old. He has been on similac alimentum since he was 5 weeks old. I am slowly introducing him to the total comfort similac. I started yesterday. The question I have is how fast should I increase the amount to mix? Right now I put one scoop of total comfort with 2 scoops of alimentum for a 6 oz bottle. So far he has been good. No discomfort or crying or hard tummy!!!!
