can you explain the diff? formula...

Can anyone explain the difference between casein and whey dominant formulas? What are they?
Kaleb was on S26 Gold stage 1 (whey dominant) and we've just decided to go and try this again as the stage 2 has been majorly constipating him (casein dominant) - could this be because of the difference?
We found Nurture Gold blocked him up really badly too first time round - any users of this formula could you please check to see if it is whey or casein dominant as we're trying to understand the root of his problem!?!

I think.... as casein is harder to digest it is usually in the hungrier baby formulas, stage 2 formula is still whey based but has more iron in it. Fay is quite picky with meat so it was suggested we change to follow on to ensure she had enough iron intake.
That's my take on it anyway and certainly the case with Karicare, also Follow on has less fat so that they arehungrier for solids IYKWIM

Kaleb has always had problems with constipation but had started 'going' by himself when he was one stage 1 and eating solids (he only gets fruit and vegetables and now some meat but no baby rice etc.). Then when we changed the formula ('cos we thought we had to) he started to get really blocked up again and ended up with a rectal tear but we perservered because we thought it was just his body getting used to the new one. It's been about 3/4 weeks and he's still pooping this little pebble sized clay like poos and seems really uncomfortable doing so. He's still not getting any rice etc. but we've started giving him more water (thank goodness for hot days since he wouldn't drink it otherwise!)so the only thing I can put it down to is the formula change?!?

Might try the 3/4 scoops (at this point we'll try anything!!! so sick of doctors, plunket etc. saying "give him water" "he'll grow out of it"). We too make 180ml bottles for Kaleb but we're lucky if he finishes any of the daytime ones. The first bottle of the day, the one before bed and his dream feed are really the only ones he'll take without a fuss. Babies aye?

I know S26 (stage 1 and onwards) was the one they said not to use with Kobe for that reason and suggested heinz nuture because its whey domanint. Luckily we never had any problems with constipation!

I would say - if the other formula worked, and worked well, then go back to that, it will still take a bit for his body to get used to it again and to get over having had the other harder stuff, but hopefully should be back on track again soon.
