That's great to hear.
As head judge for several major contests, I've seen too many daddy-built entries on the tables in the junior classes. The hands-down, all-time worst occurred one year when a snaptite model appeared . . . with reasonably nice paint job and perfectly-aligned stickers. The entrant was 3 years old and daddy (and mommy) insisted he was some kind of genius child progeny who actually spray painted the lustrous finish himself. No one believed it except daddy and mommy. The young entrant didn't have the least interest in any of the models on display or for sale in the swap meet, let alone "his own."
The paint finish was, by the way, very consistent with the finishes on a couple of daddy's models.
We got to the bottom of it when we asked the young entrant how he did the paint job on his model. He had no clue it was even painted! We awarded three places in that class, but that year there were only two entries. The other entry was obviously built by the 6-year-old who entered it. We awarded first place to the 6-year-old's model and second place to the 3-year-old's entry. When we called out his name, he wasn't the least bit excited and had to be ordered (by daddy and mommy) to come get the award. Not common for young builders.
And, oh, yeah, one other thing. Daddy pitched a bitch because junior's model didn't win first place. He complained that junior's model was much better, and at one point argued that "ours" was well painted while the other one was bar plastic.
We encouraged daddy and mommy to try soccer.
