OH my gosh, baby Richi keeps farting and it's almost non-stop. It's obviously got to be something I'm eating because he's breastfed. I've even withdrawn him from eating solids because he hasn't been wanting to breastfeed much. Any ideas? he's also been crying almost all the time for the past few weeks and I cannot figure out a reason or source. I'm thinking it's time to call the doctor.
