Because the baby’s stomach capacity is relatively small, the amount of each feeding should not be too much, so it needs to be fed once at an interval of about 3 hours to meet the needs of the baby. There are certain differences in the timing of formula feedings for babies at different stages, and not all babies are fed once at an interval of 3 three hours. For babies less than 2 months old, feeding is mainly on demand, when the baby cries, with no clear interval. For babies aged 2-6 months, it is necessary to make the baby gradually develop the habit of eating on time, so as not to lead to disorders of the gastrointestinal tract. It is recommended to feed once at an interval of 3 hours, and 120-150ml is appropriate each time. Babies older than 6 months old can be fed once at an interval of 4 hours. In short, there are individual differences in each baby’s body condition and food intake, so you need to figure out the right feeding method for your baby. In addition, you can feed your baby the right amount of plain water between feedings.
