Those wood blocks that your mother and father played with which are still at Grandma's house are a link to your parent's childhood.
These links to our past can now be found again.
There was a time when manufacturers went with what was new and exciting for them.
This meant lower cost of raw materials and less cost in shipping because of the low weight.
But plastic blocks are just not the same.
It has been proven that with these new materials comes with exposing our children to new chemicals.
Many of these new chemicals are harmful to the mental development of our children.
There are others that can cause long term health problems.
Wooden blocks and toys have been around for centuries and have never caused any more harm or danger to any child other than the occasional splinter.
This can be remedied with proper sanding.
There was a time when the blocks were painted with lead based paint, but that also has been solved with only lead free paints being used now by manufacturers of wooden toys and blocks.
Just like Lincoln Logs, simple wooden blocks are made to last generations, not just a child's younger years and then disposed of like most plastic blocks are at present time.
Every year there is a new study emerging that has found a new danger from the use of plastic intended for food items and exposure to children.
The main danger with plastic toys is that small children place them in their mouths and chew on them.
This releases the hidden dangers of the plastic.
Keep your children safe and give them what has been around for centuries with wood blocks to play with.
