Hi, i have an 11 day old baby who is feeding on nan pro gold. For the first 3 days she was fantastic and only cried when she wanted something, but then she just started crying all the time. You can hear the wind in her belly and feel it rumbling but it just wont come up and is making her so uncomfortable. Im not sure if it is her formula or not. What is the best formula to prevent so much wind? Thankyou so much
