Kids this age (10U and 12U), I think you keep 1B at first and do not rotate or "wheel" your infielders. Consider who is typically your 2B at this age. She is typically your weakest infielder. You definitely want to get the out at first if you are making the play there, and the percentage goes down when you have your weakest infielder covering that base on a bunt. As the girls get older, your second baseman will be good enough to cover successfully, but with younger kids I just don't think it's worth taking the chance that you don't get the out.
If you have to consider who your 2nd baseman is and you are worried about their ability to get the out you have two choices in TB. 1) Work hard with that player aside from practice to make them better. 2) Find a new 2nd baseman.
Even at it's lowest level of TB play you should be picking players who at least possess the ability to play well if given time and effort from their coaches. So as a coach there is not longer a place to hide players on the field. We cover 1sr from second and it has worked every time. We do not miss assignments on a bunt as it was something we worked extensively on in practice. Why....B/C at 10U PA SB Dad's statement is somewhat true. Coaches are still trying to "Hide" weaker players. It is also common that defending a bunt is not given too much time in practice. If you can use bunting as a strategy of the game it can be very successful whether you actually bunt or merely show it for a few pitches.
