My opinion, it depends on age, experience, and how your dd progresses. Everyone learns at a different rate. Some kids can fall out of bed hitting like a beast, some are not so fast on the uptake. My dd (14) is small and always struggled with hitting until last year. I only took her to occasional clinics for hitting. After the routine of middle schools ball, she really started to put it all together. She puts the ball in play on almost every at bat now. She is now to the point where she is trying to turn those ground balls into line drives. She currently sees Sheliah Gulas at Leffew about every other week, and her swing is steadily improving. They have great hitting instructors over there between Sheliah, Jen, and now Tess Sito.
