To add to what Nettle said, hatchlings are pretty fragile. Not in the way that your kids can hurt them, but in that they are susceptible to respiratory illness (RI) when they are exposed to the cooler air, especially when it happens frequently.
It's usually recommended that you don't take your turtles out of the tank until they're adults (4"+). Even then, make sure they seem comfortable being out of the tank. If the turtle hides in his shell the whole time, or makes a b-line for the nearest hiding spot, then he's probably not too comfortable outside his tank.
