Regarding diet products, you are allowed to consume those while breast feeding, but careful with them as they all contain aspartame or mannitol, which can cause flatulence (excessive gas) and this could indirectly affect your baby. So consume them moderately especially the carbonated beverages, which not only cause bloating, but also impede the uptake of essential nutrients from the gut into the bloodstream.

Food items to avoid include cabbage, broccoli, cauliflower, fava beans, chickpeas, or anything that you notice causing you indigestion or bloating.
