I would imagine, a normal politician would have been warned by an advisor to only put one child up on stage to speak. It can be incredibly risky, especially given this is not a group skilled in the political arena.  To put each and every one, with the exception of the young boy, and have them all deliver, is phenomenal and speaks volumes about Trump that might not be coming across on T.V.  When his daughter expressed how she knew her dad would be the first to call when she was having a difficult time,  was a good moment.  I think Don Jr. has a future in politics should he so desire. His speech was flawless. 

 

I also wonder if the Melania speech hiccup was an accident.  There's no such thing as bad publicitiy and a speech that would have otherwise only been viewed by people whom they already have in their corner, now millions more have watched it, and out of those, there will be many whom watch the rest.   I believe the way Trump was able to stay in the news by being over the top, this as well could be just a sneaky way of creating interest while gambling on people's doubts not to convict.  After all, the only person really taking the fall is the speech writer himself.  Kinda brillant or incredibly risky.  Who knows.
