the advanced made my baby so sick and they don't make the regular any more and my preemie has now started on isomil and is not growing as good.

for babies with low birthweight, failure to thrive or other feeding concerns. It has 22 calories per ounce and should be used with the advice of a pediatrician or neonatologist. I used one can of this when my babies were 6 lb. newborns and it gave them gas. Again, I'd stick with breastmilk, but for all you other mothers of multiples who cannot produce enough milk and are concerned about weight gain, this might be a good bet. Be careful though because relying too much on formula might cause your milk supply to decrease so pumping with a quality electric double pump is good insurance for milk supply, but I've digressed...
