Boys like boy gifts.
The best gift is time with his dad. In other words, something you would enjoy doing together. Make sure if its something you would really enjoy that you leave room for him to be a full participant.
Boys wants to be like their dad, so something that helps them be more like dad will be very welcome. Things they see you do and cherish.
Finally, boys are boys, which is to say, competitive, inquisitive, imaginationary, bold, fanciful, and tinkering.
Some of the steaders were kicking around ideas. Here’s the list for what its worth. Nothing on here is essential to the happiness of you and your sons. These are just ideas.
Merry Christmas.

A surprising recommendation from one of our guys: depending on age, maturity, and desire to expose the lad to the realities of the Great Game, intel world, and geopolitics— Animorphs complete set.
