Breastmilk can be stored at room temperature for six hours at 22-24 degrees Celsius, out of direct sunlight. If it cannot be consumed within a short period of time, it is recommended that it can be stored in the refrigerator at -18°C under refrigeration, usually for three days. You need to heat it when you want to use it, and feed the breast milk to your child in time after heating. Because breast milk is a highly nutritious substance, it is very easy to spoil, especially in summer, so it is best to feed it to the child within 15 minutes after heating. Since breast milk contains nutrients and some immune factors necessary for baby’s growth, it is the ideal food especially for babies under six months old, and it is best to consume fresh breast milk. It is recommended that women who are breastfeeding should consume more pork feet soup and pork ribs soup, which can promote the secretion of milk, and also pay attention to the supply of vitamins. Maternal women should pay attention to a reasonable diet, try not to be partial, and eat more high-quality protein foods as well as vegetables and fruits, such as chicken, fish, lean meat, eggs, milk, apples, bananas, peaches, tomatoes, etc., which can increase the content of protein, vitamins and minerals in breast milk, thus improving the quality of milk.
