Hi, I know how you are feeling. My daughter had horrible gas before we even left the hospital. The doctor told me to give her mylicon (as in the message before) It will not hurt your baby at all and you can give it to them quiet often go per label instructions of course. But it really helps. I don't know if you bottle or breatfeed, but either way make sure you are holding her at an angle when you are feeding her she will get less air this way. If the gas is within a little while of eating and you think it may be this, try burping her more often. If you can give a little more information I can give you more specifics about it. Tell me if you are breast or bottle and how often you are burping right now. what about when she/he seems the most uncomfortable. What about spitting up? I went through it all with my daughter and had a wonderful pediatriction. So, let me know these things and I will give you all the information I have.
..I look forward to hearing from you. And above all keep smiling. I know its hard but it does get better. Do you have other kids or is this your first?
