Easy to use Enfamil bottles

When the hospital sent us home after having Cameron, they sent us home with these small glass ready-to-use Enfamil (with Iron) bottles that are pretty nifty. Just screw the nipple onto the bottle and you're good to go. No worrying about finding a good sized bottle, measurimg out the formula etc. Just open, attach and go. Makes it easier for Dads to get up and tend to baby for those 2am feedings that happen oh so often so mommy can get some sleep. Who needs sleep right men? Am I right?!? Enfamil Lipil with Iron
