One-year-old babies with large stomachs should consider gastrointestinal gas accumulation or their own stomach volume, children because of individual differences and different growth and development, their related organ tissue development is also different. Some babies have a larger stomach volume, so they show symptoms of a bulging abdomen, so they eat relatively large amounts of food in terms of feeding, which can easily lead to an increase in gastrointestinal burden and gastric power, requiring parents to control the diet. If your baby has a cold abdomen or eats food that is not easily digested, it will lead to excessive gas production in the stomach and intestines causing abdominal distension, and physical examination often shows a bulging abdomen, accompanied by nausea, abdominal pain or increased exhaustion, so you need to take oral probiotics to help digestion and absorption, and reduce the intake of food in moderation.
