Dress Affordable baby garments for flower girl

I'm currently breastfeeding my one month old baby. But she is very gassy to the point where she just cries because it hurts so much. I do leg exercises with her, I've tried the football position, also cut dairy out of my diet (that was the nurse said to do). I was wondering if there is anything else I could do or is it time to go to Prosobee? Dress Affordable baby garments for flower girl
