To be honest Yael, they're all pretty much the same. They all differ ever so slightly but have to meet the same requirements so, essentially, are all as good as each other. I did find, however, that Nan was closest consistency to breastmilk and that S26 gave DD bad constipation. As BW said, AR is thickened so unless you have reflux issues, I'd probably avoid it... although I'm not sure if it will benefit DD's failure to thrive? Being thicker it would take longer to absorb nutrients... but at the same time, can tire them out quicker trying to get it in...

We used Karicare Delact for DD (one of the few lactose free ones available for us) and found that there were a couple of Karicare formula's that were often unavailable. They were having to be changed frequently or low manufacturing or something annoying. The longest period I went without being able to source DD's formula was 4 months. I was lucky that I had a stock at home which got me through the first month (they anticipated stores would be restocked within that time frame). After that, I had to call the hotline each week to get my week's supply sent in the post. They happily did this and it cost me nothing.
