Yes if that's a decision that the child and his/her family make because its best for the family....Happens all the time in college...Student gets a C in one of their course major classes and the student re-takes the class to get a better grade. Or student decides to take a biology course during the summer at a Community college because its easier, is that unfair??
People need to let this all go and remember when they graduate not one person asks them "were you a hold back"...They look at their transcript and their extra circular activities and maybe just maybe one of their coaches offers up a recommendation for them and they got a decent job. Isn't that what this whole journey is about...people need to forget about all the other nonsense. All the accolades I received when I played and not one person...no one gives a Sh_t....quite living through your kids life and let them define themselves.
