I never think it's too early to begin thinking about how you can prepare children for adolescence. My hubby is actually taking one of our sons on their first "Father-Son" trips this weekend. Jeff loves to kayak, so they are going white water rafting at the Ocoee River in East Tn, and riding a duckie together down the Nantahala River across the state line in North Carolina. But the subject matter of their conversation will be serious.
I don't want to go into too much detail, but I do want you to check two CD/Tape series out. Preparing For Adolescence
Passport to Purity
I 100% guarantee these are great. Consider doing a trip with your child by the age of ten.
