The thick, yellowish milk that comes in the first few days after birth is called colostrum. Colostrum is very rich in proteins, vitamins and minerals—just what your newborn needs. It supplies large amounts of white blood cells and antibodies that protect your baby from infections. It also cleans her intestines of the residues that build up before birth.
When a child’s immune system reacts to a particular food that he eats, he is said to suffer from a food allergy. Some allergies are permanent and very serious. A child with a known allergy to a particular food must never eat that food. It’s important to always take allergies seriously.
There are various reasons why a child may have a stuffed‑up or runny nose: crying, environmental factors (e.g., heat, humidity, dust, animal hair, tobacco smoke), or colds or other infections.
Eating well means opting for meals and snacks made up of vegetables and fruits, whole grain foods, and protein-rich foods, especially plant-based ones.
