What is the biggest kid fair in SG? Is there anything interesting?

For me personally, I really like the baby fairs organized by Babyworld/Mummymarket. They're usually held every 3 months at the Singapore expo and have hundreds of vendors participating. Good deals can be expected here and I normally stock up my toiletries here. I usually buy brands such as California baby and Mustela because there are much much cheaper here. Supermom fairs for me a little more space constraint as compared to BabyWorld but there have a wider variety and activities available for kids. The last fair I went held by them (i think it was last year October) at Suntec, they had an indoor rock climbing area for kids and my daughter loved it so much she went up twice!
