Depende siguro kung ilang taon na. Sa preschool, I think I think what's essentially more important is to establish good study habits. Yung alam nila na pag study time, study time talaga. Yes you can also make learning fun para mas ma-enjoy nila yung study session, pero you still have to make it clear to them na there's a time for free play, and a time for fun studying - na magkaiba yon. With my nursery student, ganun kami everyday, 15-20 minutes study time sa bahay, except for weekends. After that, she can play na. Every once in a while, like when we're on the road, I 'quiz' her. Like now they're doing subtraction, out of the blue tatanungin ko sya, and we make it like a game to pass time habang nagbibiyahe. Or I point out objects and we practice spelling naman or alphabet sounds. Stuff like that.

Enjoy naman sya, naprapractice pa.
As a parent, tutok din talaga. Mageffort ka to sit down with them and review schoolwork, or assist them with homework. Pero NEVER do their homework ha.

May nakita ko sa school ng anak ko last time, nakalimutan gawin ng anak nya yung homework, ayun, sya ang gumawa! Nakakaloka lang.

Assist them lang with homework ha, let them answer on their own, guide ka lang with instructions ganyan, so they learn how to do it.
IMO naman, it's normal for parents to feel the desire na gawing honor student yung anak nila - even in a stage as early as preschool, especially if you see their potential, na alam mong kaya nila. Pero, based on my experience, what you have to control is how you motivate them to excel, minus the pressure. It's challenging to do that actually, pero dapat ganun talaga - para they know na hindi kailangan perfect, but they should always do their best.

You can take cues from your kid, for example pag nagrereview kayo tapos after some time nakikita mo na pagod na, stop ka muna. In my daughter's school, there's also a mom like that in Irtwisted's situation, na alam kong gustong-gusto din pumasok sa top 10 yung anak nya, ngayon nakikita ko sila reviewing lessons sa play area/waiting area before the kids go into the classroom. I was thinking perhaps wala sila time to do that at home, pero naisip ko lang kawawa naman yung bata kasi nasa play area sila, lahat ng classmate nya naglalaro, tapos ayun yung bata, nagrereview na parang may exam lang.
