E.K.
My daughter was like that when she was younger. I would try not having her do the activities in the first place - you will save time, money and frustration. Kids at that age don't know what they want and to push them is asking for more trouble down the road. She will likely grow out of it and will learn to stick with things as she gets older and finds something she really is interested in. Also, these activities...are you interested in her doing them or is she interested? From my experience, it's better just to not do them and let her form her own ideas about what she would like to do when she is a little older. Good luck to you!
