Each year I share about my children packing shoebox gifts for children in other countries. We send these with Operation Christmas Child (OCC), an initiative run each year by Samaritans Purse, an evangelical Christian charity that I travelled to Belarus with, in 2012.
Every year I read the debate about whether people should join in with OCC as they are a Christian charity and each year it makes me smile when non-Christian friends point out that you can't have Christmas without Christ and is it really surprising that a Christian charity is spreading the message of God's unconditional love with a gift box and the opportunity to learn more about Christ if the recipient so wishes?
Whilst I'm totally happy with my decision to give via OCC and I feel sure they are not pushing Christianity onto unsuspecting children in other countries (I've seen a distribution with my own eyes after all), I do totally understand that some people feel dubious and would rather give through a different charity and there are loads. Have a google of your local area and I'm sure you will find an initiative often run through organisations like The Salvation Army, The Royal British Legion or The Rotary Club.
