FH has three boys - ages are 16, 15, and 6. I am planning on incorporating them into the ceremony in some way and would like to do it at the point of exchanging rings. I want to say a few things to them basically just telling them that I am here for them and will promise to care for them to the best of my ability. What is a gift that I can get the boys that they would like and keep? All I can find is jewelry online, but they don't wear jewelry! The older boys love shoes and fashion and of course the little one loves pokemon and video games...but sentimental for a teenage boy? Suggestions please!
