If you’re breastfeeding exclusively you are technically eating for two. Just remember that one of you has a stomach about the size of a walnut so you don’t need to double your calorie intake.
If you’re feeling hungrier than usual reach for healthy snacks
Most women can produce plenty of breast milk by eating 1800-2200 (or more) calories per day. If you’re feeling hungrier than usual reach for healthy snacks – such as chopped vegetables, low fat yoghurt or fruit, and avoid high-fat, sugary treats that provide little nutritional value.
You’re likely feeling very thirsty so stay hydrated. Caffeine and alcohol can pass into breast milk so try to avoid them, and make water your main source of liquid.
