youth softball

Question
My daughter is 9 years old 55lbs and about 4feet 2 inches. I have her taking batting and fielding pratice with charlie frazier, brother of todd who just made team usa,for an hour every other week.She wants to pitch so next week charlie will do 1/2 hour with her and then Jackie, a college softball pitcher for 1/2 hour. Is this to much, not enoughand do you have anyother suggestions. Also what size bat should she use.  

Answer
She needs to use a light fastpitch bat.  I'm not sure off the top of my head what size she needs, but she needs to be able to have control.  The bat should not look like it is swinging her.  I think every other week is good...I give some kids lessons every week.  As she gets older and stronger she should be pitching every other day for 45mins-1 hour.  She can practice as much as she wants, but make sure she quits before she gets tired and lazy because that's how bad habits form...especially when hitting.  Besides, why practice if she is not at her full potential?
