Amen Shelley. I have 9 year old and 11 year old sons. We hunt, fish and shoot firearms regularly. We started bowling a few months ago. They used bumpers at first, but, wanting to do like dad and the other adults, now they would rather not bowl then to bowl with their younger cousins using bumpers. They have their own balls, bags and shoes. In the long run, its a lot cheaper than renting each time, and for sure, more sanitary.
I am learning correct form from a coach and try to teach them as I learn. My youngest is receptive to teaching, and averaged 93 Saturday night. My oldest wants to do it his way and averaged 89. They both had fun,and that is the most important part. They are competitive by nature and in time, will both learn the proper way. Until they decide they want to, I will let them bowl like their mother.
