Need a discplince

Mother wants to discipline Ethan on his day to day routine. Basically the two main concerns are his homework and the nap time.

Homework:-
Mother wants to set a timetable on his homework like he only has 15 min to finish his homework on one subject. We need to train him or else when he enters the primary school that time where got ample time for him to finish all his homework with his current attitude.

Nap time:-
Last time he takes his nap starting from 1 o clock but recently after his homework and reading session, we actually delayed it to 2 o clock. He can take his nap time until 6 something in the evening. Well, cannot persist with this situation anymore because after he wakes up late from his nap time, he actually only can sleep around 12 at night which causes him not really can wake up early next morning. Mother wants to set the nap time from 2 to 4 then in next year he only entitle one hour nap time. We need to gradually adjust it because we were afraid he will attend the afternoon class when he is in primary one.

After adjusting this two main issues then he got spare time to play. Let's hope the plan can work. Mother will start from today.
