When did the baby start feeding complementary food in stages? When can the baby eat snacks?

After the baby is half a year old, you can gradually add complementary food to supplement nutrition. If you eat snacks, the gums will itch when the deciduous teeth erupt for more than 7 months. You can eat some snacks that are ground. My baby also began to eat English Iger 1 grade grinding rods from this time. Its wave shape is very close to the baby's gums, and soot is often suitable for baby grinding teeth.
