If you are looking for a job related to baseball, you could also consider working as an umpire, where you would make calls and enforce rules. A high school diploma is the minimum educational requirement for most sports officials, but some leagues will also require you to complete additional training programs. Another option is to become a fitness instructor, where you would teach individuals and groups of clients general exercise practices, like weightlifting or aerobics, to help them improve their health and wellness. Fitness instructors need a high school diploma, and professional certifications can boost job prospects.
If your child is receiving proper batting instruction that has them utilizing the strength of their legs to power the swing you will be hard pressed to find a new bat that is too heavy. If finding a heavier bat is of interest, the place to shop is Goodwill or a second hand sporting goods store. My 5’ 2” 85lb, 10 year old son swings a 27”, 22 oz bat that I bought for $5 from Goodwill. I am not a cheapskate, but that is the only place I could find a ‘good’ bat for him. I would guess the thing is 20 years old. I am not suggesting you take your child to Goodwill and buy them an old bat, but if you want to find a bat that is a few ounces heavier that is where you have to go.
