Food accumulation in small-month-old babies may manifest as fever, poor appetite, poor sleep, bad breath and stool changes. 1. Fever: Some babies may have fever after accumulation of food, which may be manifested as fever in the palms and feet. 2. Poor appetite: the baby’s appetite will become smaller after accumulation of food, and the appetite will decrease obviously. And when you touch the baby’s stomach, it will feel a little hard and bulging, which means that the baby’s intestinal flatulence is caused by the accumulation of food. 3. Poor sleep: the baby’s stomach is bloated and uncomfortable, which often affects sleep and is accompanied by crying. 4. Bad breath: Babies with food retention often suffer from indigestion because food stays in the belly for a long time, and eventually their breath becomes heavy and has a sour odor. 5. Stool changes: the baby’s stools are often very dry and hard, constipation can occur, some babies can be manifested as diarrhea, and stools have a sour smell. If the baby’s symptoms of food accumulation are not relieved, or accompanied by other symptoms, you should go to the hospital in a timely manner, to identify the cause and give targeted treatment.
