I want them to still believe while they are still young

This year I requested in lieu of Christmas gifts for me if I could buy gifts for a family whose children would otherwise have nothing this year. I was told her kids have never had any new toys or even a new bike ever. I am able to buy them their christmas dresses, new toys and 3 new bikes for each child. when asked by my grown sons what I want I tell them to take me shopping so I can add to this families gifts. I also told the mom not to tell them where the gifts came from…just Santa. I want them to still believe while they are still young –Sylvia
