R.,
Poor you and poor baby! ;( That's so rough on you both when baby isn't happy!
My son couldn't tolerate regular (milk-based) formula at all. We put him on soy formula, and he did great! We never had any other problems with him after that. We also used Mylicon drops when he did get gas -- they worked wonders on him!
My daughter has been exclusively breastfed until about 2 weeks ago(now she gets just one bottle a day at night). Even with just the one bottle of formula, we noticed that she was starting to cry and have bad stomach pains and gas last week. We switched her to the soy formula, and she's had a great week!
Best wishes to you! I hope you and your sweet little one get some relief! Good luck!
Also, just thought of one more thing. We swear by the Dr. Brown's bottles! They're great! They seemed to help both of my kids have less gas and issues. You can buy them at most any store that sells baby products (Babies R Us, Toys R Us, Target, etc.).
