I have clothes and toys I'd like to donate to a charity that my kids have outgrown of. Any recommendations mummies?

There are a few places you can donate your items at. If you use Facebook frequently, there are help groups like PARK $2 Project which often collates information of donation drives and charities which require such items. Do also consider donating to MINDS as it helps the intellectually disabled gain confidence in manning the retail outlets and sorting out donations. The money raised is used to fund their programs. http://www.minds.org.sg/Shop.html
