Where can I get preloved toys for my preschooler? Thanks!

You can definitely get pre loved toys on Carousell. There are so many sellers on Carousell selling away used toys. There are also a couple of preloved baby stuffs groups on Facebook which you can join. One of these groups is Preloved SG Babies Goods. The moms in the group do sell toddler and preschooler toys as well.
