For ages 6 and 7
Glove - We recommend your players glove be 10 inches or smaller so they can control it. Try not to purchase a cheap synthetic mitt. A used mitt from Play It Again is a good option as they are cheaper than new mitts and will likely be well broken in. It is very important to break in your child's glove prior to the beginning of practice. There were many occasions last year where a player was able to get their glove on a fly ball, but unable to make the catch because the glove was too stiff. The best way to break in a glove is to use it, but there are also lots of other suggestions you can find online.
Bat - Bats will be provided by the league but if you want to purchase a bat, we recommend it be 26 inches or shorter and under 16 ounces. Most teams have several pretty good bats that are fairly light, and you will see over the season that the most important thing for these young players is to be able to generate good bat speed. A slow swing with a too-heavy bat is very ineffective compared to a fast swing with a light bat.
Helmet - I also recommend that, if possible, every player get their own helmet with a face mask. Your player will be able to use it for years to come and you won't need to worry about health issues like the teams that had lice outbreaks in previous years. The helmets provided by the league are invariably too big, and its difficult for the kids to hit and run the bases with a giant helmet bouncing around on their head.
Cup - Boys will need to wear a protective cup. Sport stores have an item called Super Sport Shorts for under $20. They size them by pant size.
