Question
How much should a 40-day-old baby eat every day?
Answer
Newborn babies have a small stomach capacity, with the initial neonatal stomach capacity ranging from 30 to 35ml, increasing to about 100ml at 3 months, 200ml at 6 months, and 300 to 500ml at 1 year. Breastfed babies have a stomach emptying time of 2 to 3 hours; formula-fed babies have a stomach emptying time of 3 to 4 hours, while water has an emptying time of 1 to 2 hours. At this age, the baby can drink 100ml of milk, with intervals of every 3 hours.
