Ehm, just wondering, is the nursery the same as the daycare?
In that case I need to revamp the starting town lol, since there's a daycare-thing there.
Anyway,
Chou Toshio , when will be the first encounter with the evil team? It could be in this town a la Team Plasma in BW, but it can be later in the game as well.
IV Checker wil definitely be helpful, but it's not a good idea to put it only in this town (imagine all the backtracking without Fly .-.). It could be a service in the pokemon center, like some sort of computer or guy that is present in every center.
Also I'd like to say that, in my opinion, the normal trainers (like Youngster Joey or something) won't have a full team of top percentage Pokemon (ha). Three pokemon is a core, not a full functioning team, and therefore the battles aren't as difficult. Ofcourse when you enter the Victory Road or those kind of routes later in the game, the trainers there will have teams of 4-6 Pokemon and will be more difficult to handle, but as for now I think simply rewarding the Trainer with money like the normal games do should be the best option, since there are Centers in like every town.
Also by typing this, I came to think about something: Double Battles
In DPPt, you have certain areas where you team up with another trainer and engage in Double Battles, as well as just fighting twins and the like in double battles. BW also introduced the Dark Tall Grass (you get what I mean I hope) where you have Double Battles vs wild pokemon. The thing is, Doubles strategies are different from Single strategies, so should these double battles be present in the game pre-E4?
