What size baseball bat to use.

Question
My son is 10 yrs old and weighs about 65 lbs. He wants a new baseball bat, but how can I tell what size is good for him.

Answer
Sean,
    There are arguments to both using heavier and lighter bats.  Most importantly is getting the correct length.  As long as the bat is the correct length your son will get accustomed to the weight of the bat.  The goal is to have bat control, bat speed, and proper hitting mechanics.  My recommendation would be to get a light bat for bat speed and control.  Using a heavier bat can make for bad hitting habits at your sons age.  Weight doesn't become an issue until he gets older and uses wood bats.  As he gets older the weight ranges get smaller and smaller.  The argument for a heavier weighted bat is that it gives a greater impact force on the baseball with less bat speed.  The lighter bat is opposite with a lower impact force but higher bat speed.
    The length of the bat should be based on your sons height.  When standing up straight the bat should measure two to three inches below the waist.

Thank You,
