C&G Comfort having opposite effect

[fairygirl]

My LO has been on this formula for 10days now. I decided to try it after she was struggling with trapped wind and other remedies just aggravated her mild reflux. But now she seems uncomfortable for hours trying to poo, and only going once a day, her movements start like clay and end like water! She burps after feeds with perserverence and sometimes brings up a bit of milk. Other problem is wind from the other end, I know C&G warn this will be the case but she really struggles with it!

Probably switching back to a 1st milk, heard Hipp is better on their system.

Any similar experiences?
