1. Newborns less than 4 months old should not consume bird's nest, because newborns less than 4 months old can't absorb the nutrients of bird's nest directly, and are prone to indigestion. After 4 months of growth, it can be consumed in small quantities. When simmering, you need to simmer it for a longer period of time to make the bird's nest more soft and sticky, which will help your baby to digest and absorb it better.

2. Bird's nest should not be consumed by patients with colds and fevers, because most of the immune system functions of patients with colds and fevers are reduced, and the functions of their own organs are affected, especially the respiratory and digestive tracts, which are the most obvious. During the period of cold and fever, it is better to suspend the bird's nest and other supplements, so as not to affect the expulsion of the disease. When the cold and fever get better, then bird's nest and other dietary supplements can be used to strengthen the body's resistance and immunity. If there are only cough symptoms, no fever symptoms can be eaten.

3. Bird's nest is not suitable for patients with untreated cancer or advanced cancer; it can be used to restore vitality, replenish nutrients, and improve immunity after recovery from illness. However, there is no help for patients with untreated or advanced cancer.
