I get gifts for all my GC, or maybe a giftcard or money for oldest GC if i cant find suitable gift- very early 20's and 16 year old, but their parents (MY 'kids' and SinL & DinL) i just give a token gift wrapped up to open on xmas day- the usual 'smellies' and gift sets etc, or occasionally a small item to do with their hobbies etc. I certainly wouldn't gift them money- but as you can't see them really to give a gift, as someone else said, maybe a voucher or gift token, or book token maybe? Or double up on a coffee shop egift card or the ones you can get for 'cinema tickets for two' or 'dinner for two' etc- might be much appreciated as they can have a date night as a treat.??
