Don't give too much pressure on yourself and your kids. For me last year, just treat it as a fun time with my kid ("play" toys with strangers). I never tell my kids that it's interview and never blame/appreciate him on his performance. Kids are very sensitive and they can feel mama's pressure even we try to pretend in front of them. Actually most N1 schools are not interview kids but the response of parents. Thus, relax! The result will be out of your expectation!!
P.S. We almost got all offers from applied schools finally and what I tried to do was only keeping my kid in good mood during interview.
Totally agree. If our children already know all the stuffs in the interview (matching color, shapes, singing…), why do they still need to go to school? I just don’t understand how can they expect a 1 year old kid to know so much stuff.
