My daughter and son both had to be on gentlease but we found out that Target makes basically the same formula for $10 less than the Enfamil brand, but it is still a powder...neither one of my kids liked the pre-made liquid, it actually caused them to spit up more. Also we use the 3 chamber container like somone else mentioned, it works great for trips. Just fill the bottles with water and then add the powder.
