How do u change your formula 1 to 2 for lo? Stage 1 states 0-6 months, does that mean that when lo is 6 month old you will change to formula 2 straight away or what do you do?

Transitioning from formula 1 to formula 2 should be done gradually. I read that by mixing in a bit of formula 1 with formula 2 during the first few days of transition will help, baby will be less likely to notice if there has been a change in taste.
