This formula is great for babies who have frequent spit up. It comes only in liquid, 32oz bottles, which are between $5.50 and $7 each, depending on the store. The container it comes in is wonderful, as it has a lid and is very easy to store. The bottle is made of plastic, which is great for recycling. It does not have a foul smell, like the Enfamil Nutramigen. My son spits up excessively normally. We have not been able to use regular formula since he was about a week old. (Now is 8 months old). We switched first to Enfamil A.R., which is good, but it is VERY thick, and it is not easy to store...
