... I'm not an instructor, so I made it a point to not allow my kids to even use gear in the pool until they were certified. I didn't want them to inadvertently pick up any bad habits.
Hmmm. Let's see:
0. Swimming and drown-proofing lessons from a very early age
1. Skin-diving (snorkeling) skills
2. Al 50/63 (or LP 45/50) with plastic backpack with nylon harness; never leave a tank standing unattended
3. Regulator recovery (simple regulator) and buddy breathing
4. Scuba ditch and don
5. Never hold your breath (always continue breathing normally)
6. Always ascend
very slowly, exhaling, and switch to snorkel upon reaching the surface
7. Absolutely never mess with scuba gear, whether in or out of the pool, without me (Dad) or Mom with you!
I, too, am not a scuba instructor. Yet, I was extremely comfortable introducing my then-young daughters to scuba in a backyard pool.
Allowed me to gauge whether they had a real interest. Years later (last Spring term), my eldest, a college junior now, decided she wanted to get certified. Her twin sisters, two years her junior, are expressing interest now.
FWIW.
