My DD is 8yr old. She has slowly started pitching for about a year (meaning that she will pitch about 1 once a week and took off most of the spring and early summer.) Recently, she is pitching more often,like 2-3 times a week. I have talked to her PC about her pitching more often, he suggest that she should only pitch about 50 pitches 1-2 days a week and 1 long session of about 1 hour. Today, I counted her pitches and she pitched 50 pitches within 15 mins. I was wondering if this is not enough pitches?
