Quoting Nussie:" For the last 5-6 days my daughter has been having really bad gas. She always has since she was born but ... [snip!] ... or could it be something else? Should i take her in to her pedi or is there anything else i can do to help? She is brestfed."
Nooo this is way past normal gas
I would def get her to the pediatrician asap and ask them. She may have a sensitivity to something you are eating/drinking. (My sister had to go gluten/dairy free while she was breastfeeding because my nephew was allergic and had terrible gas and was not gaining any weight from it) Have you tried the gas drops? I found placing my daughter across my lap and patting her back until she got some gas out very effective for when normal burping did not work well.
