You asked:
* Naomi drinks Nutramigen - where do I buy this formula - drugstore, pharmacy?
Do I need a prescription? What price may I expect to pay?

Nutramigen is a product of Mead Johnson (Enfamil formulas).  My son drinks
ProSobee, which is also a product of Mead Johnson.  Although I have never
looked for Nutramigen, I think that it is carried in the same stores that
ProSobee is.  Although it may not be as common.  The cheapest place to buy is
a discount store like Wal-Mart or KMart.  I know they have Wal-Mart in
northern Florida since we were just there last month.  If you can't find one
of these most grocery stores will carry formula.  I don't know about the
price of Nutramigen, but ProSobee runs anywhere from $8 to $12 per 14 ounce
can of powder.  I hope that this is a little help to you.  Good luck and
enjoy your vacation.
