Re: What could be going on?
If you formula-fed, they wouldn't blame breastfeeding. But they'd still blame you. You're too nervous. You hold him too much. You don't hold him enough. You're not warming his bottles the right way. You're using the wrong formula. You need to put rice cereal in the bottles. You need to put him on a schedule. You need to take him off the schedule. Everyone is a critic and they will always find a way to make it about what you, the mom, are doing wrong!
Your doc gave you absolutely ridiculous advice about breastfeeding. Seriously, she made it up out of thin air. It is absolutely incorrect that your milk "can't keep up" with your baby's demands- just ask all of us who have had babies who have survived and thrived on nothing but breastmilk (and the occasional cheerio) until they were toddlers. The more often you nurse, the more milk you make, and you don't need to wait for your breasts to "fill up" in between nursing sessions in order to provide sufficient nutrition for your baby. Obviously you are doing just fine- your baby is growing nicely, you have abundant milk, and you're seeing lots of wet and poopy diapers!
I am willing to bet money that the culprit here is teething. Even if you don't see the teeth coming in, you can be sure they're moving around down in his gums, causing lots of discomfort. Will your LO sleep in his swing at night? If so, I'd use it! If not, well, this too shall pass. You're doing a wonderful job, mama!
