The danger of eating complementary foods at five months is that the baby develops bloating, diarrhea, abdominal pain, fever or eczema. The baby’s own gastrointestinal function at 5 months is not yet well developed and is relatively fragile, so if complementary foods are added at this time, the gastrointestinal tract is not able to digest and absorb the nutrients contained in the food, resulting in indigestion and food retention. The baby may also cause abdominal pain, bloating, diarrhea and other discomforts, which may sometimes cause the baby to cry or even develop fever. Moreover, if the baby is allowed to eat complementary foods too early, it may also increase the chances of eczema and other skin diseases. Do not add complementary foods randomly to reduce the stimulation of the baby’s gastrointestinal tract. And add complementary foods should pay attention to the principle, generally from a small amount to a large amount, from one to many, from thin to thick.
