Doctor's answer:

Hello: There is no need for a certain gray top!
1) Gradually adapt the baby to it. At the beginning, start by getting the child accustomed to flavors like soup, juice, etc., to pique their interest. You can dilute the soup the adult drinks 2–3 times and cool it to a temperature similar to body temperature, then feed it to the child before breastfeeding. Juice can be mixed with water and fed directly, or mixed with formula.
(2) Gradually increase the amount and variety of complementary foods for the baby. When introducing a new complementary food, do so gradually, starting with a small amount and gradually increasing it. Hasty introduction can easily lead to failure. At 4 months of age, start by adding egg yolk, beginning with 1/4. After a week, if the child's appetite and digestion are normal, increase it to 1/2, and gradually increase it to a whole yolk. At 6 months, the child can start eating whole eggs. Do not introduce two or more new foods at the same time. First introduce a complementary food that the child has never eaten before. Once the child has adapted to it, introduce another new food.
(3) From thin to thick, from soft to hard. For babies aged 1–3 months, you can give them thin porridge, vegetable soup, juice, etc. As the baby grows older, gradually introduce thicker porridge, soft noodles, biscuits, etc. If a child does not like a new complementary food the first time, it may lead to a dislike for it later. Therefore, the first time you introduce a new complementary food, make it softer and more palatable to make it easier for the child to accept and avoid hard food causing vomiting.
(4) From fine to coarse, from powder to pieces. The complementary food introduced must be made as fine as possible. Fresh vegetables should first be given as a vegetable soup, then vegetable puree, and finally vegetable pieces.
(5) Frequently change the variety of food. Varying the types of food makes the diet more "diverse," both
