What foods should be avoided when breastfeeding? What helped you with milk production?

Hi! Little one will be making his grand debut by next week and I’m excited (and nervous and anxious and all the feels) to bond with him and breastfeed.

I’m looking for advice on what foods I should avoid while breastfeeding? I heard there are some that promote gas and discomfort.

Similarly, what foods did you find that helped you up your supply?

Thanks in advance!
