dd#2 was like that - and man I was loosing my mind!
Gripe Water was a life saver - can use it as early as 2 weeks old and give up to 6 times a day. Works within 5-20 minutes - amazing stuff.
Everyone else here has given you great advice. I caved and gave dd a bottle of formula because i thought my food intake was to blame for her gas - and she IMMEDIATELY threw up the formula - guess it was my dummy button for her not wanting that
Stick with it - it really does get easier!!
