An eight-month-old baby can have three milks and two meals during the day, and can have two milks and three meals after one year old.
Give him breast milk in the morning at night, and drink milk powder, rice flour and some other complementary foods during the day.
Formula milk can be added. For such a big baby, the total amount of milk per day should be above 600ml. He may not like it because he refuses to drink a bottle. He can drink from a cup or a small bowl. Many babies like to drink milk or soup like this.
Drink plenty of water, every time the baby wakes up, take a shower and sweat. Eight-month-old babies should have teeth, so they can develop the habit of drinking saliva after drinking milk and eating, which is good for teeth.
In addition, you can add some fish sauce, which is not as easy to digest as egg yolk and fruits and vegetables. At first, you should add less. If the baby has a good digestive ability, you can feed it a little every day. If you can't digest it well, you should reduce it, feed it once every other day and exercise your baby's stomach slowly.
