How old are my little tail 2' s children and brother?

The heart in My Little Tail 2 is a baby 18 months old, and her brother was born in 2000. The age gap between them can be said to be great among brothers and sisters.

The age gap between the two is extraordinary, such as adults, such as adults in babies. When I am hungry, I know how to find my brother Wang Ruihan and how many milliliters of milk I need to drink. In the face of my brother's poor cooking, my heart chose not to be exposed, but all this was seen by the audience, calling me to want a baby too much. An An is only 2 years old, but his behavior is much more mature and independent than his actual age, which may also be related to his brother Nie Zening's usual education. Nie Zening's usual dialogue with An An is to treat An An as an adult instead of a child. Therefore, although Ann is shy in a strange environment, she blends in quickly, which may be achieved by a very safe child.
