Congrats mate!
My litle girl is only 2, and she holds the decals for me before they go into the water.. She is one of these kids who simply loves stickers of any sought.. So when she asks me for the 18th millionth time "what are you doing".. I say that I am playing with my special stickers!....So now the wife doesnt get angry with me when I build, as I am spending "quality time" with her!..
Good luck to you and your wife!
