It reminds me of reflux. My twins suffered from reflux at 3 months on. One day (stupid me), I unthinkingly ate hot wings. That evening when I breastfed, they sucked as they normally would but then pulled away and cried. Then they would suck again and pull away and cry all over again. They were clearly hungry, but was in too much pain.

Might not be the formula itself, it could be the teet. Different teets have different flow rates and are made for different ages and stages (keep in mind that babies don't read the teet packet where it shows the type per age, so they don't always comply to the rules of the company that produced it. LOL ). If the teet is too fast or too slow in flow, babies will often behave that way.

Maybe ask your doctor, some new born's stomachs can't handle normal formula. We were told our son was lactose intolerant for ages but one day I accidently gave him some food with milk in it and he stomached it fine. I asked her what was going on and she said sometimes babies can't stomach the regular formula and need to be put on the lactose-free or soy formula. Sometimes they display the same symptoms as having a lactose intolerance. Learn something new every day!

Watery poo is an indication of either overfeeding or lactose intolerance ( i'd go with the latter) try a lactose free formula.

All the best

i used the nestle gold one with my 2. Alex hated the S26 and Karicare.

it maybe the girls dont like the taste of it and it upsets their tummy.

Hi,

I had my youngest on Karicare Gold plus first, he was very fussy and unsettled.  His stools were very watery and loose aswell, and extremly stinky.  I changed him to the normal S26, and he feed alot better, slept better and his stools became better.  You might just have to try another formula, and find one that suits them better.  Some of the formula that have the pre-biotics can be upsetting for some babies.

Good luck.

my son was the same ( he had S26 Gold),  i found when he got whingy it was cos he ate it to quick, try switching brands for a few weeks ( there more or less the same price) or you can get formula thats solely designed for bubs with watery stools, sorry not much help
