You're still eating for two
Sometimes your baby can suffer gastrointestinal discomfort from something you've eaten. It takes between two and six hours for food to find its way into your breast milk, so if your little one seems uncomfortable, think about what you ate that day. Eliminate the suspected culprit from your diet to see if that does the trick. You can reintroduce that food a few days later to gauge his response and to confirm your suspicion.
