Question
My baby is over 7 months old and still can’t sit up by herself, nor has she grown any teeth.
Answer
By 7 months, a baby should be able to sit up for a period of time with support, and should also be beginning to grow lower incisors. Considering the possibility of rickets, it is recommended to supplement with 400 international units (IU) of vitamin D daily. At this stage, you can introduce complementary foods; for babies between 4 and 6 months, you can add rice porridge, baby biscuits, nutritious rice flour, and thin gruel to increase calories; for those between 7 and 9 months, you can introduce soft bread, toasted bread slices, and cookies. The food should include egg yolks, fish puree, tofu, animal blood, etc., to increase protein, iron, and vitamins. Additionally, introduce vegetable purees, fruit purees, and juices to increase vitamins A, B, C, and fiber. At 7 to 9 months, babies can consume fish, eggs, liver puree, and minced meat to supplement more protein, iron, zinc, and vitamins A and B.
