So it doesn't help with colic, which probably is silent reflux in quite a few cases, which is never diagnosed and resolves itself when the baby is older.
For us, it did actually seem to make winding easier and quicker, dd did seem to scream a lot more than the other two children, we did use infacol which helped a little. In her case, she was the only child, and sometimes was overstimulated. I used to rock and cuddle her to sleep, she used to fight this like a gooddun. One day I got fed up of this struggling and popped her in her cot, she went off to sleep on her own, it was a revelation.
Ds1 was a very calm baby and would get himself off to sleep every time, was just the wind stopping him, infacol certainly helped with the endless winding process.
