Yes, it's important to ensure you're getting enough essential vitamins, particularly Vitamin D. Vitamin D is crucial for healthy bones, both for you and your baby. Most of it comes from exposure to sunlight. However, if you live in a place with little sunlight, especially in winter, you may not get enough Vitamin D, so supplements may be recommended. Additionally, make sure to get enough calcium, as breastfeeding can reduce its levels. Aim for four servings of dairy products per day, such as milk, yogurt, or cheese. If you prefer non-dairy options, consider nuts, tofu, sesame seeds, and leafy green vegetables. One serving equals roughly half a cup of green vegetables or a small 50g piece of cheese.
