Kirkland Signature Infant Formula with Iron — 

We switched from Similac Advance after 1 month of bottle feeding, and noticed a significant change in stools.  The Similac was much softer and seedy, whereas the Cosco's Kirkland formula was uniform and much harder.  This was accompanied by strain and crying during bowel movements.  All of these are signs of constipation, requiring adding water to the diet, which is not normal for a 1 month old.  This change was 100% correlated to the formula, and we even switched back after a month of using Costco's Kirkland formula to Similac when we ran out, and the very next stool was back to normal.  If you search online, you'll find several other people who experienced this same problem.  We solved this originally by giving 1oz of water to our daughter throughout the day.  However, I tried switching 1/3 of the Kirkland forumula for Similac and this seems to have corrected the problem as well, and is still much cheaper than switching to Similac alltogether.  Another difference between the two is that Cosco's Kirkland formula is very foamy when you shake it up and this doesn't go away, leaving lots of foam at the bottom of the bottle.  Similac is foamy initially but they have some ingredient that cuts it down as the baby eats.  Switching 1/3 of the forumula with Similac got rid of this problem as well.
