Help getting disabled kids their dream gift

my 2 grand kids are disabled and and they both have one wish that we could not full fill being that we struggle bc of a house fire and we just got a house in time for Christmas we were able to get them a couple of things but they each only wanted one thing on their Christmas list n I was not able to get it the two boys only asked for one present this year. They each asked me for one thing and I was not able to get them. The one thing they asked for two gifts and I couldn’t even afford them so I was wondering if I can get some help to get them two gifts that they asked for
