BOUGHT A SECOND HAND SOFT TOY?

Is it for a young baby?

When your child is very young everything is supposed to be sterilised and clean  as babies will always put everything in their mouths.  

Having had 3 children myself  I understand how important it is to a parent to make sure that everything a child puts into its mouth is clean.  Because of this you may have been put off buying soft toys for a young child second hand as some of them are not machine washable.

TO MAKE SURE AN ITEM IS CLEAN AND GERM FREE 

Wash it according to the label - usually just sponge clean.  (Milton or Dettol solution on a sponge is a good idea)

When dry simply place it into a freezer bag and place it in your freezer for 24 hours.  

This will kill anything that may be on the item and then can leave you worry free.  Your baby will be able to chew on it all they like.

Babies are expensive little bundles - so if this means you consider 2nd hand because you now know you can clean them then GREAT.
