It is a good choice for children to eat bread and milk in the morning, but it also depends on their physique. Some children are allergic to milk, which is not appropriate. But for growing children, milk is an important source of calcium. You can still drink more if you can.
There is a lot of controversy about milk now. It is also reasonable to argue that a person should drink more milk in the first half of his life and not drink milk in the second half.
As for bread, whole wheat bread is more nutritious and suitable for adults and children.
Wish the baby a healthy growth.
