Hi June,
Think we might be in the same situation, looking for activities for our 2 year old for socializing purposes and to keep them occupied. I may not know all that is available, but from what searching we have done, this is what i know....
If you are looking for preschool/playschool/kindergarten, then usually half days. The ones that usually accept 2 years old are usually the franchisers, for example RealTots at USJ, Kinderland, Krista (some) and Fungates. I know some kindies in Subang accepts 2 yo...
If you are looking for activities, then it is usually music or gym type i think...
At the moment, my kid attends Kizsports gym... So we are hoping to find more activities for him too.
Hope some of this info helps. If you need any of the contacts, let me know...
