Sounds like your in the same boat as me. My second (last) is 2 and my daughter (7) and I are working on getting a breeding thing going. My wife would be the one boxing and my daughter and I would be crying. Haha.
As for naming bugs I don't think I'll ever get there. I held onto a male dubia for a long while in case I wanted to start a colony but eventually let my beardie have at him. Haha.
Yep mine are the same age. My Daughter turned 7 last month and my son turns 2 next month, its going to be our last. My daughter didn't want to come out, so my Wife had to get a C section, and then they said they have to do it again with my son. So while they were doing that, she got tied.
My wife actually loves the roaches, just the Hissers though. She hates the Orange heads, but the Halloween Hissers, she likes playing with them and saying look they have a little family lol.
Cant say I blame her, I like holding the Halloween Hissers too, but the OHs man, IDK, they move so fast and like dig into your skin with their spikes, the Hissers are so much more Chill.
My Daughter is kinda Meh on the cham breeding, she wants snakes, lots of big snakes. She caught a garter and we let her keep it for a few days in a Tank, and she has been obsessed ever since. She is always asking for a new snake, my wife hates them, so she let it go and told her we would get her one later, and she has yet to stop asking.
We were talking about Cham breeding last week, and my Daughter said "We aint breeding no Chams, We are breeding SNAKES!" That would change though, once she seen the babies hatching.
