During the first busy weeks after having my son, I used Enfamil premium ready to use infant formula! It offers the same great nutrition of Enfamil premium powder so I knew my newborn was getting all of the vitamins he needed. This formula is really easy to use, you just open the can and pour it into the bottle and it's ready to drink. The only negative is that after you open the can it requires refrigeration and so the second use is not as convenient when you have to take the time to heat up the bottle! I also would have liked the can to be more resealable. The top of the can sits on top in the fridge nicely but it's not sealed on which I would have liked. Although the ready to use formula is more expensive to use then the powder version, it's great if you have a newborn or not a lot of time to mix bottles or just don't want to deal with the potential mess and formula scoop measuring. I think this Enfamil ready to use formula would be great for working mothers!
