We first used enfamil. She was colicy, gassy, and had reflux.
We switched to Good Start and while she was still colicy and still had reflux, the gas was much better and the symptoms of reflux eased a lot too.
My daughter was miserable on Enfamil. Good Start helped a lot after we did the switch...but then she got worse again. Turns out she has a milk allergy. I don't think it had anything to do with switching, though. She's now on soy formula. She's doing a lot better =]
yuppers!! i had my6 daughter on all the expensive formulas at first..thinking they had to be better...but my daughter was spitting up after every feeding!! i then switched to good start, and it was perfect!!! i highly reccommend good start!!
