Savings bonds. Always. But, if you have to give something in hand, which I always do too, face paint, fingernail tatoos, play nail polish, matchbox cars, most boys that age are getting into Tony Hawk (clothing) Stickers, bath tub or beach stuff, Music for young children, Movies or movie tickets. By the time they grow up, and if you keep giving them a bond for many years, they will have a good amount to take with them for needs than wants.
