Nutrition for breastfeeding: how to fuel your body and your milk supply

It can feel like a lot of pressure to "eat perfectly" when you are breastfeeding, on top of all the other anxieties of new parenthood. This guide is about a simpler, calmer way to think about food, focusing on fuelling your body, not on a complicated set of rules.

Many parents worry that what they eat, or do not eat, will negatively affect their baby or their milk supply. You might hear advice about special "lactation foods" you must eat, or a long list of things you must avoid. This can be incredibly stressful when you are already exhausted and just trying to find a moment to eat at all.

The most important thing to know is that your body is designed to make nutritious milk for your baby, even if your own diet is not perfect. The best approach is not about strict rules, but about giving your body enough fuel. Your body uses a lot of energy to produce milk, so this is not a time for dieting. The simplest advice is often the best: eat when you are hungry, and try to eat regularly.

Hydration is also a key piece. You do not need to force yourself to drink huge amounts of water, but a good, simple goal is to drink to thirst. Many parents find it helpful to keep a large water bottle nearby and take a drink whenever they sit down to nurse or pump.

When you do eat, you can focus on balance. Try to include a mix of protein, carbohydrates, and healthy fats when you can, as this will help keep your own energy stable. This does not mean you need to cook complicated meals. A handful of nuts, a bowl of oatmeal, a cheese sandwich, or an apple with peanut butter are all wonderful, simple options that give your body the fuel it needs.

It is important to know that while your diet matters for your own health, your milk supply is primarily driven by "supply and demand": how often and how effectively your baby nurses or you pump. While some people notice a supply boost from certain foods, like oatmeal, you do not need to eat anything special to make milk. It is also a myth that you must avoid foods like broccoli or garlic: in most cases, you can eat whatever you like, as long as it makes you feel good.

The best guardrail is to listen to your body and your baby. If you are ever genuinely concerned about your milk supply, or if you consistently notice that your baby seems very fussy or shows signs of an allergy (like a rash or green, mucousy stools) after you eat a specific food, the right person to talk to is your pediatrician or a board-certified lactation consultant.

Eating for breastfeeding is simply about eating enough to keep yourself nourished and hydrated, so your body can do its work. By focusing on "good enough" meals and staying hydrated, you are doing a great job of fuelling both yourself and your baby.
