Aquaduck,
St James kindergarden is at Tanglin village lor.
I dun like Suntec, especially crowded during the weekend, plus the pool is cold (according to my brother, my niece switch from suntec to St James). I prefer St James, the pool is small but it's heated, sheltered, free parking and private.
Basically, it's just teaching water confident. Max is 6 babies a class. Splashing, kicking, surfing, etc etc.
I like that place also becauce after that, I can bring bb to Go Go Bambini to play for awhile, it's free entry for bb below 1yr old.
I also dun mind going for Kampong playhouse trial too.
