smithy - i haven't wanted to really comment about the constipation and formula issue as i'm not FF BUT, i have read a couple of times where you've said about making the formula more watery. now, as i said, i'm not FF so i'm not sure, but is watering it down a good idea? i'm pretty sure some of the reason that the formula companies were copping so much flack overseas was because people were unable to afford formula once their milk dried up, so were watering it down to make it go further... i would be worried about DD getting as much nutrient as she needs if you water it down

i know you switched to the thickened formula to try and stretch out her feeds and get her sleeping longer - but if it's going to give her so much grief, i would be going back to the other formula and copping the 2 hourly feeding! we went through 2 + months of DD only dirtying once every week or 10 days, and she would SCREAM in pain when it happened - so i understand why you're trying everything you can to get C past this - just make sure that watering down the formula is not going to be detrimental to her.
