Formula milk...

During my first pregnancy i didn't had breast milk for the first few days. So hospital feed formula to my daughter. Fortunately they feed the same brand (Enfa) I intended to give her. So there was no issues on the formula for her once we return home. Now I am expecting no. 2... I intend to feed Enfa for this baby also. What I am afraid is what if hospital feed different brand. And once I am at home how to switch to Enfa? Please don't suggest to BF... If I have BM I will definitely BF. Thanks
