When his older brother is taking online lessons, the younger child will often shout, or create other disturbances. That makes it harder for the older boy, because if he misses something in a lesson, he has no way of picking up on it later.

Most parents don't even know how they are supposed to help their kids learn at home. Without any timetable or dedicated learning environment, children have difficulty concentrating.

Wong tries to help her sons by setting up timetables, which she makes them follow. She does what she can, hoping she can teach the boys something by playing games with them. Wong acknowledges that she's no teacher but she hopes her efforts to adapt toys and even the furniture into learning experiences will offer at least some progress.

She still worries about the possible long-term effects the situation has on the boys' physical and mental health. She's also worried they may take a long time to re-adapt when classes resume.
