While there isn't a single, precise measurement for a 14-month-old's stomach size, it's helpful to understand how a baby's stomach grows during their first year. A 14-month-old's stomach capacity is slightly larger than that of a baby between 6 months and 1 year old.
A child's stomach between 6 months and 1 year old is about the size of a small grapefruit, and about 5 times smaller than an adult's. This means it can hold approximately 200-250ml of milk or food (roughly 1 cup). By 14 months, it is reasonably safe to assume that the capacity is slightly larger, perhaps capable of holding closer to 250-300ml. This is an estimation because stomach size varies between individuals, just as adult stomach sizes do.
Keep in mind that babies and toddlers eat smaller amounts more frequently than adults. They need nutrient-dense foods to support their rapid growth and development.
