Breast milk is thin and clear, what to do?

Did you know that 90% of breast milk is water? So, if your milk looks thin or clear, don’t worry—it’s perfectly normal! Trust that your body produces enough milk with sufficient nutrients to nourish your baby.

1. Why does breast milk sometimes appear thin and clear?

Breast milk is composed of up to 90% water. Foremilk, produced at the start of a feed, is clear and thin because it’s higher in water and protein. Hindmilk, which comes later, is thicker and creamier due to its higher fat content.

Colostrum, which is yellowish and clear, is only produced during the first 1–2 days after birth. Therefore, describing milk at this stage as thin and low-quality is not entirely accurate.

According to experts, the quality of breast milk does not vary significantly between mothers, regardless of the milk's quantity or whether it appears thick or thin.

Additionally, the thickness or thinness of breast milk is influenced by the mother's physical makeup and not solely by diet. Foremilk is naturally thinner than hindmilk, which is why doctors recommend feeding for 15–20 minutes to allow the baby to access the nutrient-rich hindmilk.

Breast milk quality also depends on the presence of harmful chemicals or toxins. The milk may lose quality if the mother is ill or consumes unsafe food.

Moreover, each baby has a unique ability to absorb nutrients, and environmental factors also play a role. Therefore, a baby's weight gain is influenced by more than just the perceived quality of breast milk.

2. Is thin and clear breast milk sufficient for the baby?

Thin breast milk is common among postpartum mothers and often causes concern about whether it provides adequate nutrition for the baby.

In reality, the thin appearance of breast milk does not impact its ability to nourish the baby. Most breast milk has the same basic nutritional components, and the key difference lies in quantity, not quality.

Breast milk can be divided into two types:

  • Foremilk:
    Unlike colostrum, which is yellowish, foremilk is the milk released during the first 10 minutes of breastfeeding. It is clear and thin, resembling rice water. However, it still contains essential nutrients such as proteins, vitamins, minerals, and water for the baby.
  • Hindmilk:
    Hindmilk is produced later in a feeding session and is thicker due to its higher fat and protein content. It appears slightly yellow and is a critical source of nutrition for the baby's growth and development.

What to do if breast milk is thin?

The only way to improve the quality of breast milk is by adjusting your daily diet and lifestyle.

3.1. Enhance the mother’s diet

A perfect diet for mothers to increase milk supply and make it thicker and more nutritious involves ensuring sufficient intake of essential food groups.

  • Add green vegetables and fruits:
    Incorporate plenty of vegetables, fruits, and whole grains into meals. These foods are rich in essential nutrients, vitamins, and fiber.
  • Include DHA for the baby’s brain development:
    Foods such as fish and meat are rich in iodine and protein, providing ample DHA for both mother and baby. Eat fish 1-2 times a week and increase meat intake to meet protein requirements.
  • Consume calcium-rich foods:
    Include calcium in your daily diet through foods or milk. Calcium supports the baby's bone development and prevents osteoporosis in mothers.
  • Drink enough water:
    Ensure a daily intake of 8–10 cups (about 2 liters) of water to stay hydrated and maintain sufficient milk production.

3.2. Adjust daily routines

A proper routine contributes significantly to better milk production and quality.

  • The importance of rest after childbirth.

After giving birth, a mother's body is often very tired and exhausted, which significantly affects both the quantity and quality of breast milk. Make sure to rest and relax so your body can recover and produce the best milk for your baby. Only when a mother is truly healthy can she produce abundant and nutrient-rich milk.

Additionally, the thickness and quality of breast milk are greatly influenced by the mother's mental state after delivery. A relaxed and positive mindset helps the milk ducts function more effectively, improving milk production and quality.

  • Breastfeed regularly and correctly:

If you don’t breastfeed often or use the wrong technique, your milk supply might seem low or thin.

Breastfeeding correctly and regularly helps mothers maintain a consistent.

Breastfeeding correctly and regularly helps mothers maintain an abundant and high-quality milk supply each day. Additionally, proper breastfeeding posture is crucial. Milk should be evenly drawn from both breasts; the baby should fully empty one breast before switching to the other. Nothing should be added to breast milk. While breastfeeding, mothers should stay relaxed, and the surrounding environment should be quiet, free from dust or harmful substances.

Mothers need to observe whether the baby is getting enough milk by checking their satisfaction after feeding. The most important thing is to meet the baby’s nutritional needs adequately.

  • Engage in light physical activity:

After giving birth, a mother’s body is still very tired, so strenuous activities should be avoided. However, light and gentle exercises can help mothers feel more relaxed, reduce the risk of postpartum depression, and stimulate milk production.

These gentle exercises also improve the mother’s health and enhance the quality of breast milk for the baby.

  • Avoid Stimulants Completely

Stimulants such as alcohol, beer, and tobacco can inhibit the functioning of the milk ducts. According to specialists, mothers should stay away from these substances while breastfeeding.

  • Other Methods

In addition, here are some methods to help make breast milk thicker and more nutritious for your baby:

  • Massage the breasts to stimulate milk production.
  • Avoid strong-smelling spices that can cause internal heat for both mother and baby, such as pepper, chili, and garlic.
  • Drink 2 to 3 liters of water daily.
  • Clean the nipples with warm water before breastfeeding.

Breast milk is the best source of nutrition for newborns and infants. Therefore, mothers are encouraged to breastfeed exclusively for the first six months to strengthen the baby's health and immunity.
