I think that 3 practices a week plus lessons 1-2 days is sufficient for a 10 yo.
^^^'She asked less' is understandableWhen my dd first started playing she would ask to go to the field everyday. The more we got into team practices and lessons, she asked less. At first I took it as laziness but then I realized that I was the one wanting to practice everyday and was pushing too hard. We don't do lessons now and the team only practices twice a week. At this point, working at home two days a week is mandatory. Except she is playing bball nonstop and is about to try out for h.s softball, so maybe not "mandatory" .
3 days of Team practices and one or two lessons a week is definitely an abundance of softball. Except for they are Guided by the adult running those. There is no time for her to be her own player developing her own purpose.
2 days a week of hitting lessons in my opinion is better for her to do one day of those on her own
