I'd also like to join Kindermusik but I only know about classes in Central and TST which are quite far away. Would also be interested to know about other good playgroup in or near TKO area!
There is also one in LOHAS Park. They have 2 classes for 6-18 months. 10am and 11 am and class duration is 45 mins. A good place to mingle and very good atmosphere. Teacher very children friendly. In fact she is very nice to talk to especially all these mommies's talk. My babies with her for 2 terms. We really enjoy it. They are very full, you might need to just drop your name for waiting list. Good luck
