Can you recommend some good stores for educational toys and flash cards for toddlers?

You can browse through the products offered at Right Brain Babies: http://www.rightbrainbabies.com.sg/products/educational For flash cards, you can also try making your own (that is if you have any time to spare...). You can refer to these two links for tutorials on how to make a set. A tip for making these is that the paper weight matter so getting thicker papers may be helpful. http://domanmom.com/2015/08/word-cards/ http://www.mummyshomeschool.com/shichida-flashcards-how-to-make/

I made my own flash cards actually. Just simple A4 size papers and I write in Bold with red markers. Just simple daily words that we often use. I also draw red dots for simple maths. I follow the way Glen Doman flash cards did theirs. You can get thicker papers if you like. I did it for my boy and now reuse it for my lil girl

There's quite a wide variety out there, including ELC (now part of Mothercare), Leapfrog, Fisherprice, Playskool, Baby Einstein. Can buy cheaper ones online at the usual baby websites like pupsik studio. For second hand, there's carousell and gumtree.

ELC has many choices for educational toys. You can find these at Mothercare stores.

I bought mine from carousell. Picked up the glen doman Flashcards
