弟弟 doing homework

弟弟 starts to have homework after almost 2 months start his kindy life. However, he doesn't like to do homework and always try to skip it in the afternoon. He wait until mommy came home from work which is usually around 7 or 8pm, then only he will do his homework. At that time, he claims that he doesn't know how to write and ask mommy to guide him.
Mother check with his school teacher and feedback from teacher is 弟弟 can write in school. Every letter that teacher teach him, he is able write by himself.
However, he act differently when at home. He even choose the page that he likes to do as homework, not follow what teacher assign to. Sometimes, he will just write partial, not complete and said :"finish, 弟弟 don't want to do"
Kind of headache to deal with 弟弟 especially on homework. Mommy and Ah Mah have to force him to do the homework everyday.
