Answer:
D. Babies should not eat solid foods until they are one year of age.
Step-by-step explanation:
The food base of a newborn is breast milk. Preferably, the baby should breastfeed for at least six months. Baby nutrition can be supplemented with bottle feeding. When the baby comes close to one year old, it is possible to introduce baby food, which consists of beaten soups, without solidity. The solidity is not adequate because babies at this age do not have complete teeth or motor coordination to swallow solids. This will be introduced gradually after the first year of life.
