I found a course for 18 months kid at 葉氐和唱團 at Taikoo. The course is 5 days from Mon to Friday from 09:30 to 11:30 (2 hrs). The monthly cost is HKD2850. I will send Reginia once she reaches 18 months.
There are options for 2 days or 3 days but the cost for 2 days is above 2000. Therefore, I prefer choosing 5 days.
I could not find playgroup nearby(long queue list) and with no choice, I will send Regiona to Tutor time at the meanwhile. The monthly fee is HKD1850 per month on every Sat for 1.5 hour each time.
