hey congratulations.  coaching the development team is a great start as there isn't a lot of pressure on you to perform.  It isn't a lot different from coaching a club team except you have a lot more motivated players as they have been selected to play in the team. The harder part is that that this is the first year that any of the girls will have played in a rep team, so you could have issues with parents who believe their daughter is the next diamond superstar.  You experience will depend if your association supports and communicates well or not.   Just do your best, watch the other coaches to see what they are doing and to see how the association wants their coaches to coach, and have open and honest communication with your team and you will be fine.  Have a great year.
