The color of breast milk can vary depending on the fat content consumed by the mother. Nutrient-rich colostrum breast milk is usually golden yellow in color and is produced in the first few days after birth. After a few weeks, mature breast milk will be white in color. This change in color reflects the changing nutritional content according to the baby's needs.

High-quality breast milk usually has an aroma similar to cow's milk with a slight sour smell after being frozen or thawed. If breast milk has a very strong sour smell after being stored in the refrigerator, it could be a sign that the breast milk is no longer suitable for consumption. Breast milk with a soapy, alkaline aroma indicates a high content of lipase.

The fat and lactose content in breast milk makes it have a texture that tends to be liquid and smooth. Breast milk at the beginning of breastfeeding (foremilk) is more watery compared to mature breast milk (hindmilk) which is thicker because it contains more fat. Foremilk is usually produced more at the beginning of breastfeeding to quench the baby's thirst, while hindmilk provides more calories and nutrients.

One indicator that a baby receives quality breast milk is healthy weight gain. Babies who receive enough quality breast milk will experience weight gain that is appropriate for their age. At the age of 0-3 months, babies typically gain around 150-190 grams per week. At the age of 4-6 months, weight gain ranges from 90-120 grams per week.

The frequency of urination and bowel movements in babies can also be an indicator of the quality of breast milk. Babies who receive enough quality breast milk will urinate about 6 times a day with a volume of about 45 ml each time. Knowing the signs of quality breast milk is very important to ensure that little ones get the nutrients they need to grow healthy and strong. Source: Fimela.com.
