I have a jar in my kitchen where I put all the loose change I collect. My DS has several piggy banks in his room where he saves all the change he finds. Before I had DS I would save my change for a year and then cash it in for Christmas gifts or a weekend away for DH and I. Since DS started school, I can't seem to save it as well. I am always dipping into it for milk money or snack money for school. When my DS banks get full, we take it to the bank. I allow him to spend some of it and the rest goes into his savings account.
